In a medium sized pan, over medium-high heat, cook your ground beef until no longer pink. Strain out any excess grease.
Return to heat and add the onions, mushrooms, bell peppers, and seasonings. Cook 5-7 minutes until the veggies are soft.
Stir in the ketchup, Worcestershire sauce, cottage cheese, and cheddar cheese powder. Cook until all the cheese melts.
I like to put all the buns on a cookie sheet with a slice of provolone on one side. Broil on high 3-4 minutes until the bread is toasty and the cheese is melted.
Add 125g (heaping ½ cup) of the beef mixture to each bun. Enjoy!
