Roast Beef Burgers

This is a recipe for getting true roast beef
flavor inside a grilled beefburger or hamburger.
You can top these with any of the usual,
I like these simply with spicy brown mustard.
Use 80% lean and do not overcook the burgers.

Ingredients:
1 pound ground beef 80/20
1/4 pound deli cooked roast beef, sliced
1 slice red onion, chopped fine
1/4 teaspoon Old Bay seasoning
1/4 teaspoon ground black pepper
salt to taste

Directions:
In a food processor chop roast beef to a
fairly fine texture but not overly chopped.
Place in a mixing bowl with ground beef.
Add onion, Old Bay Seasoning, pepper, and salt.
Mix just until combined.
Make into patties and place on grill,
cook and flip to your desired doneness.
Serve on hamburger buns with toppings.
