Meatballs
Do you have a flat cookie cooling rack? Not the kind with legs that stack, but just a short, simple one? Spray it down with cooking spray, and set it on a cookie sheet. This will make the meatballs brown evenly on all sides.
1 lb of ground beef, one egg, 1/4 tsp each or garlic powder and oregano, one slice of bread finely crumbed (food processor is the easiest way to get the right size of crumbs), squish it all together.
Pat the mix out flat on a cutting board, about a half-inch deep. (Actually, it doesn't matter how deep it is, as long as it's uniform.) Now slice it up like you would brownies; I do it about 1 1/2 inch squares. The meatballs are now all the same size, and will cook easier. If you have one that's a little bigger, that's okay - it's your "test" meatball - the one you can slice open to make sure they're done.
Put them on that cookie rack, bake for around 30 min (depending on the size) at 350.
Perfect meatballs, every time.
If you want, you can even make them early and stick them in the fridge until dinner, and plop them into spaghetti sauce to warm them. Leftover meatballs in sauce (if you HAVE leftovers!) are bonus sandwiches tomorrow!
