1. In a bowl mix ground meat, red onion, corindier, 1 egg and breadcrumbs, add black pepper, some garlic, if u want u can add a little bit of Chili.

All ingredients in a bowl:

2. Mixed up and make a "big pattie" and use a little knack or u can use the baking tray or u can fry like separate small pattie burguers. I use a little knack with my mini oven 250•C degrees.

3. While is cooking the big pattie u can prepare mushrooms with ground pepper or use another seasoning, dijon mustard is a good choice. Chop de coriander and some red pepper and wash some green lettuce leaves :)

Chop the other ingredients for final step:

4. Finally cut the patties wherever u want and put on the lettuce leave, than put the mushrooms on patties, add some ground cheese if u want, add red pepper, coriander, merkén (if u have) and there u have it !
