Preheat oven to 375°F and line a baking sheet with parchment paper for even cooking and easy release.
Whisk cottage cheese and eggs until smooth, then mix in cheddar, Parmesan, and salt to form a thick batter.
Spoon mixture onto the sheet and spread into small circles about ½ inch thick to create sturdy bases.
Bake for 10 to 12 minutes until lightly set and slightly golden, then remove from the oven.
Add sloppy joe beef to one side of each base, keeping the filling centered.
Fold over to form pockets and press edges gently to seal.
Bake again for 8 to 10 minutes until crisp and golden brown.
Let cool for a few minutes so they firm up, then serve warm.
