BBQ Bacon Cheese Burgers

I know I haven't been on here in awhile.. Haven't really made anything new to post..But I'm getting back into it again. I made this about 2 weeks ago. I was just tired of regular cheese burgers. Even both my kids ate every bite.

8 slices of Texas toast, lightly toasted
1 pound hamburger
1/2 packet of thick slices bacon, any kind you like
1/2 cup of your favorite BBQ sauce, divided
4 slices of Cheddar bacon flavored slices cheese
1/8 cup finely chopped onion
1 avocado, sliced (optional)
sliced onion
sliced tomato
lettuce

Preheat a skillet, or grill, over medium heat. In a medium bowl put hamburger, chopped onion, 1/4 cup of the BBQ sauce. mix well together, but just until its all mixed. Divide into 4 equal patties. Place in heated skillet and cook until done about 5-6 mins a side. Meanwhile cook the bacon until desired doneness, set aside on a cooling rack or paper towel to let the grease drain off. Toast the toast, lightly.
Once burgers are done top with the cheese so it can melt a little. Place a slice of toast then burger, bacon BBQ sauce (divide remaining sauce among the 4 burgers, can use more if you want), then top with avocado, onion, tomato and lettuce then top with other slice of toast. You can make it a open face burger to and just use the one slice of toast.
