Use 1 tbsp of olive oil to marinate steak. Sprinkle with salt, pepper, and a little chopped fresh rosemary and season well.
Cut zucchini, onion and bell peppers into long and thin slices.
Place some of the vegetable strips vertically on one end of each slice of meat. Roll and hold with a toothpick. Repeat this procedure for the rest of the ingredients.
Add olive oil in a hot pan and sear the steak rolls all sides until cook. Add soy sauce or coconut aminos in to cover the rolls while they are still cooking then turn off the heat.
Transfer to a plate and sprinkle with sesame seeds. Serve hot with cauliflower rice, leafy greens or steamed veggies.
