Are you getting bored with plain burgers? You can always dress it up with some cheese on top, but even that can get rather boring after a while. How about getting creative?
First off, you're going to need a bun, right? Check out The Grainless Baker. They make some really yummy hamburger buns! You can also check this site out. I haven't tried the buns, but you can order them and give them a try.
You can then get some ground beef (choose your desired fat percentage) and 1-2 TBSP of water to each pound of ground beef, 1/2 tsp salt, and 1/4 tsp pepper. Use a 1/3 cup measure and measure out a portion for a ground beef patty. Split that portion in half, flatten half and then put some shredded cheddar cheese on top. Flatten and place the other half of the ground beef mixture onto the cheese, pinch the edges so that the cheese is INSIDE your burger. Put that burger on your grill until the internal temperature is 165F.
Some great toppings for your burger are: pickles*, onions, lettuce, tomatoes, sliced avocado, more cheese, and don't forget that Heinz Ketchup is gluten free, as well as French's mustard!
*Vlasic Pickles are gluten free. You can go to their website, click on "About Us" and then on "Q&A" to find their statement concerning their pickles being gluten-free.
