Wash the broccolini.
Heat a large pan with olive oil. When hot, place the broccolini stems next to each other in the pan. Sauté on one side for 5 minutes over medium-high heat. Flip the stems, add a splash of water and sauté until the water has evaporated (3 to 5 more minutes). Season with sea salt.
In a small bowl, combine the olive oil, sesame oil, tamari and maple syrup.
Place the broccolini on a serving plate while still hot or wait until it has completely cooled down. Top with the marinade, red pepper flakes, sliced almonds and toss. Serve right away.
