For the stuffed tortillas, peel one onion and cut into small cubes. Peel the second onion, halve it and cut into strips. Wash zucchini and cut into slices about 1 cm wide.
Wash tomatoes, cut 2 of them into small pieces, the other into 8 wedges. Blend the avocado pulp with the juice of half a lemon and the chili powder, then mix in the diced tomatoes and onion.
Sauté the zucchini in a hot pan with olive oil, then fry the steaks for 1-2 minutes on each side and finally warm the tortilla patties a little in the pan.
Fill the tortilla patties with the avocado cream, onion and tomato slices, minute steaks and zucchini. Add a few squeezes of half the organic lemon, season with salt and pepper.
Fold tortillas and serve with mixed leaf lettuce.
