Low carb burger

We've been experimenting with low-carb stuff.
So I wanted to make burgers, but decided to skip the bun.
Mixed into the ground beef some wheat germ, almond meal and grated Romano cheese.
While I was grilling the patties I grilled some onion slices on the side.

After flipping the burger I put on a little BBQ sauce and a slice of cheese.
When the burger was done I put a little water in the pan and put a lid on to melt the cheese.
Garnished with a slice of tomato and some slices of avocado.

Had to eat with a knife and fork, but other than that it seemed to fill the burger need.
