Just thought I'd share my personal simple recipe for meatballs, whether you want to fry them or cook them in a tomato sauce.
For 4/5 portions:
500gr top quality beef mince
Breadcrumbs (about 100gr)
Grated parmesan
1 whole egg (or 2 if necessary)
Chopped garlic or garlic powder
Chopped fresh parsley or dried if you don't have fresh.
Salt and pepper
Just mix all ingredients together, form meatballs, size depends on your preference, I get about 16 meatballs from the above doses, it depends.
I make a tomato sauce, while it's cooking, pop in the meatballs, cook for about another 30/40 mins. Then I use the sauce for pasta (rigatoni o other medium-size short pasta, not spaghetti).
An all-in-one quick, easy two-course meal!
