"Science is my background, food is my passion, and organization is my superpower"

BSc Biomedical Sciences | MSc Health Food Innovation Management

If there’s one thing I know for sure, it’s that meal prepping doesn’t have to be overwhelming.

Whether you’re a health-conscious student, a busy professional, or an exhausted parent (or two at once?!), I’m here to make plant-based meal prep easy, realistic, and even a little fun. Because let’s be real, figuring out what to eat every day is exhausting.

My mission

After years of meal prepping, I realized that the biggest struggle isn’t just knowing what to cook, it’s actually getting started and staying consistent. The decision fatigue, the never-ending grocery lists, the “ugh, I have nothing prepped” moments… I’ve been there. And that’s exactly why I created this space.

Through easy-to-follow recipes, practical meal prep guides, and time-saving tips, my goal is to help you build a system that works for you (find your very own meal prep formula)!

My educational background

I have a BSc in Biomedical Sciences and an MSc in Health Food Innovation Management, and what that should tell you about me is that I’m a science nerdie with a heart for nutrition.

When I'm not digging deep in scientific literature, I’m probably curled up with a book about ultra-processed foods and plant-based eating. My favorite thing is breaking down all that science-y stuff into simple, practical tips you can actually use in your real-life kitchen. And you better bet that I’ll silently judge you if you give health advice on the Internet without naming your source (lol).

My story

Turns out, I’ve been meal prepping long before I even knew what it was. Back in high school, when I found out I couldn’t tolerate gluten, eating at the school restaurant was no longer an option. So my best friend and I started taking turns making lunch for each other.

Then came university: full days at school, long study nights, and zero gluten-free food at the cafeteria. Meal prepping wasn’t just convenient, it became a non-negotiable.

I broke up with gluten in high school, fell in love with plant-based cooking at uni… and that kicked off 10 years of meal prep!

Fast forward to post-graduation life, I took the road of self-employment and life got... busy. Picture me living off chocolate-covered rice cakes for breakfast and crackers with hummus for lunch. Terrible? No. Nutritious? Not so much.

That’s when I went back to my meal prep habits. Refining them, making them way more efficient, and, this time, plant-based (read more about my plant-first approach to eating).

Now I teach busy people like you how to meal prep in a way that actually fits their life, whether that means prepping full meals or just getting the basics ready for the week ahead.

5 fun facts about me

I had a secret food blog at 16 (or was it 17?) where I shared my first gluten-free recipes after getting diagnosed with a gluten intolerance and trying to heal my gut. Lost the password though, so I started Cooking With Elo 6 years later.

I’m a fake vegan (according to some people on the Internet😂). I’m allergic to dairy and eat mostly plant-based but I’m not 100% vegan (read more about my plant-first approach to eating).

I’ve always wanted to write guides, somehow it's in my DNA. When I was seven or eight years old, I even drafted one called “How to Save Your Pocket Money”. My latest one is this one about the best plant-based protein sources (which is a must-read if you want to start eating more plants).

I’m convinced I make the best fruit salad ever. Try it and prove me wrong! P.S. I also have a fall version, so no excuses.

I can’t say if I’m a coffee, tea, or matcha person. I get obsessed with a drink, then move on to the next one. Lately, it’s been this salted caramel latte.

Things I get asked all the time

Are you gluten-free?

Yes, I’m fully gluten-free. Not by choice, but because my body made that decision for me. I was diagnosed with non-celiac gluten intolerance as a teenager after years of mystery symptoms, and it completely changed how I approach food and gut health.

It’s been a blessing in disguise, though. I discovered so many new ingredients after growing up on bread, rice, and pasta (no shame to my parents!), and now I have a much deeper understanding of nutrition and a more varied diet because of it.

What does your Sunday routine actually look like?

I usually sleep in a little (sending love to all the parents who can’t 😅), then make a cozy breakfast or brunch. Pancakes are a Sunday fave!

In the afternoon, I’ll typically do my meal prep for the week ahead. If you’re curious, I’ve shared a full breakdown of what that looks like.

What’s your go-to lazy meal when you don’t feel like cooking?

Probably my 15-minute cherry tomato pasta, assuming I have cherry tomatoes in the fridge. Otherwise, I always keep stir-fry veggies in my freezer and I like to make this stir fry (the sauce is so good!).

Do you teach meal prep classes?

Yes, I do! I started hosting live online meal prep classes in January 2025. It’s usually a 5-week series where we meet on Zoom every Sunday and I walk you through the entire meal prep session step-by-step. I typically run the program 3 times a year, and you can hop on the waitlist if you want to join the next round!

I've been on TV and in the press!
