Cook the rice and sides. Prepare the coconut rice and veggies (green beans or your choice of sides). If using peanut chickpeas, toss cooked chickpeas with peanut sauce.
Make the teriyaki sauce.
Sear the steak. Heat oil in a large cast-iron skillet over medium-high heat until shimmering. Pat steak dry and season with salt and pepper. Add the steaks and sear until a crust forms and they naturally release from the pan, about 3-4 minutes per side. (See notes below for temperature chart.)
Transfer the steaks to a cutting board, glaze with teriyaki, then tent them with foil and let them rest for 10 minutes before slicing and serving.
Assemble the bowls. Divide rice among 4 bowls, top with teriyaki steak, add garlic green beans, chickpeas tossed in peanut sauce and avocado slices. Garnish with sesame seeds and serve.
