I don't usually make burgers so before a few days ago I hadn't perfected a "recipe" - but a few days ago I actually made some and then repeated them yesterday, and I have to admit they were very good. Here is what I did:

- I chopped London broil (the first time) and chuck (the second time, eliminating the external fat) in the food processor. The results weren't as soft as a regular burger but fine anyway. I liked the texture of the London broil better, but the flavor of the chuck was nicer.

- I mixed the chopped meat with some salt, ground cumin, garlic powder and Worcestershire sauce. I eyed the quantities - my eye seems to be pretty good as both times they were well seasoned. I think the Worcestershire sauce is key.

- I cooked them in the pre-heated Foreman grill until medium-rare. I put a slice of cheese on them and then closed the grill for a minute or so.

And that was it.
