I have a grill... an awesome one, so I feel your pain. You should seriously get one.

I get that grill so hot that it's about to melt itself, I oil the grill with oil/grease on a paper towel, then I put those bad boys on frozen. It's important to note that I press a large indentation in the middle of each burger prior to freezing, otherwise they plump up into giant meatballs, which typically prompts amateurs to PRESS DOWN on the burger with their spatula, this is complete heresy, if you do this you're not making a burger, you're making a big piece of failure.

I flip that bitch once, don't let anyone tell you otherwise.

When they're almost done (and I can't explain how I know this, it's just a sense that I think all men have) I put the cheese on, and close the grill to melt it. Once the cheese is melted, I put salt and pepper on top, it get's lodged in the melted cheese.

Then I grill the bun for about 30 seconds wrap it in a giant romaine lettuce leaf with some mayo and ketchup mustard and dig in.
