Cheeseburger Casserole

1/4 cup chopped onion
1/4 cup chopped dill pickles
1/2 cup water
1/2 cup ketchup
1 - 1.5 tablespoon yellow mustard
1/8 teaspoon pepper
3/4 cups Cheddar cheese, sliced or grated (more if you want)
1 can 8 oz can Crescent Roll
1 Tbsp Milk
1 - 2 tablespoon sesame seeds

First, brown 1 lb ground beef and 1/4 cup onion, diced.
Next, add 1/4 of garlic dill pickle, dice, 1/2 cup of ketchup, 1/2 cup water and 1 to 1.5 Tbsp mustard. I personally have a small mustard addiction, so I used 1.5 Tbsp.
Pour all into a 9x9 Casserole dish. Open a 8 oz tube of crescent rolls, enough cheese to fit in a layer in the casserole, and about a Tbsp of milk, and sesame seeds. The recipe calls for 1 1/2 cups of cheese, I didn't really think it needed that much. If you were grating cheese, this is about 3/4 cup. Layer the cheese over top of the beef mixture.
Top with the rolled out crescent. You can make slices for steam escape if you like, this is just my preference. Next, brush milk on the top, add the sesame seeds. Bake 375 - 25/30 minutes,
