Gluten-free sandwich with vegetable burger and avocado sauce

In a bowl we mix the burger mix with water.

With our hands or a pastry cutter we shape the burger.

We brown it in a pan with a little oil on both sides for 2-3 minutes.

We toast the bread in a dry pan.

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

We assemble the sandwich by putting some sauce at the bottom, then tomatoes, the burger, grilled vegetables, and we close it.
