Grilled hamburgers with cheese
Cover the wood chips with water in a bucket and soak for at least 30 minutes.
Mix the ground chuck with seasonings and form into large patties (Add the mesquite seasoning last).
Prepare the grill, heat the charcoal, add the wood chips, then add the meat (Your grilling may vary according to your type of grill and type of meat you're grilling, etc.).
Add a slice of cheese on two hamburgers just before taking them off of the grill (You can either top all of the hamburgers now with cheese, or add cheese later.).
Cook onion slices over the stove in a cast iron skillet with enough oil to cover the bottom of the skillet (5-8 minutes or more, depending on your stove and how you like your onions).
Add mayonnaise and/or mustard to the onion bun.
Place the lettuce on the bottom bun, top it with a tomato slice, add onion slices next, put the hamburger on top of the onions, and place the top of the onion bun over the hamburger and cheese.
