I felt like making meatballs recently so I looked up a few recipes, modified them, added my own touches, and came up with the recipe below. Since lean ground beef is used (90/10 or 85/15) make sure you don't over cook them or they will be dry. This recipes makes about 36 2" meatballs so if that's too many, you can freeze them. You can easily double the recipe if you need a larger quantity. Enjoy!
Baked Mini Meatballs with Feta Cheese
1 pound lean ground beef
1 egg
1/8 cup sweet onion, minced
3 cloves garlic, minced
1/3 cup feta cheese
1/3 cup bread crumbs
1/4 cup milk
1 teaspoon onion powder
1/8 teaspoon kosher salt
1/8 teaspoon pepper
Preheat oven to 400. Coat a cookie sheet with baking spray. Mix all ingredients until well blended. Shape beef mixture into 2" meatballs and place on cookie sheet. Bake for about 12 minutes. Sprinkle with kosher salt (I always use kosher but you can use whatever you'd like. I think kosher brings out the flavor of food better.)
