When we were kids (my brothers and sisters), we used to love eating Sloppy Joe's.  We always used leftover chili for this dinner - a quick, easy, tasty meal.  For these Sloppy Joe's I decided to make them pizza flavored - served on a gluten free bun.  I know there is a lot of cheese there - trust me, the pizza sloppy Joe's is under that mountain of cheese!
1/2 pound of lean ground beef
1/2 pound of lean ground pork or turkey would be good too
1 onion, minced
4 garlic cloves minced
4 crimini mushrooms, diced
14 oz. can of tomato sauce
salt and pepper
1 tsp. ground Garlic
1 tsp. dried Basil
1/2 tsp. Italian Seasoning
1/2 tsp. ground Fennel
1/4 cup Parmesan cheese
Grated Aged Cheddar Cheese
Heat up a non stick frying pan on low medium heat.  Add in the ground meats, sauteing until brown.  Then add in the onions, garlic, mushrooms, and seasonings.  Continue to saute for another 10 minutes.
Pour in the tomato sauce, stirring to combine and check for seasonings.  Simmer for 30 minutes on the lowest heat.
Remove from the heat and stir in the Parmesan cheese.  Serve over gluten free buns, with a topping of shredded cheese.
