DD Friendly: Onion Mushroom Burger with Cheesy Tomato Sauce

This recipe is originally from Ella (The single woman’s kitchen).

Here is what you need:

Portabella mushrooms (cut into small cubes)

Onions

3 lb of 90% lean ground beef

3 TBSP grainy mustard

salt and pepper

For the sauce:

1 can tomato sauce

Oregano to taste

A handful of mozzarella cheese

Mix mushrooms, onions, beef, mustard, salt and pepper together. Form into balls and place in oven at 350F until it’s cooked through. While the meat is baking, heat the tomato sauce and add oregano and cheese. Once the meat is ready, spread sauce over it and enjoy!
