These taste especially good as a snack after an afternoon of cross-country skiing or snowmobiling. I prepare them before we go and pop them in the fridge, then just heat them when we get home!—Eleanor Martens, Rosenort, Manitoba
In a skillet, cook ground beef with onion and garlic over medium heat until meat is no longer pink; drain.
Combine the ketchup, mustard, oregano and Worcestershire sauce; stir into beef mixture. Add mushrooms and mix well. Simmer 15 minutes or until heated through. Spoon onto buttered hamburger buns; sprinkle with mozzarella cheese.
Place on baking sheets; heat under broiler until cheese melts.

Sounds yummy but can't have only 7 carbs with the bun included!
