Gluten-free sandwich with vegetable burger and avocado sauce

In a bowl, mix the burger mix with water.

With your hands or a pastry cutter, shape the burger.

Sear it in a pan with a bit of oil on both sides for 2/3 minutes.

Toast the bread in a dry pan.

Prepare the sauce by mashing the avocado and then adding lemon, pepper, salt, and oil.

Assemble the sandwich by putting some sauce at the base, then tomatoes, the burger, grilled vegetables, and close it.
