Food recipe for hamburgers. I believe it's the correct way.

So what you do.  Get a plastic container that has a lid.     A plastic container that they have at the store that has salad in it.

Then go ahead and eat the salad.

Then save the container for later use.

Then , put washed lettuce in it. Even if the lettuce doesn't need to be washed.

And mix it with the salad dressing that is orange.  Or use mayo.

Then put in the fridge for one day.  Six hours before you're ready to use it put sliced tomatoes in it.

Then, take it out of the fridge one hour before you put it on a hamburger. 

Basically, the water from the lettuce will be mixed in with the mayonnaise. Causing it to be good.
