Line two baking sheets with parchment paper or foil
Finely dice the onion and garlic.
Mix the ground meats, onion, garlic, herb and spices with egg whites. You'll need a large bowl!
Use a portion scoop (I use a cookie dough scoop) or spoon to scoop evenly sized portions of meatball mixture onto the parchment lined baking sheet.
Roll each ball individually in your hands to even and smooth out. Set onto baking sheet.
Place pans into freezer for about 30 minutes until stiff. This will keep your meatballs from becoming one large ball in the ziploc.
Pull the pans out and move balls to two separate freezer bags. Sauce can be mixed now (with the exception of cornstarch) and placed in a quart size bag inside gallon bag.
Sauce
Mix together all sauce ingredients, with the exception of the sour cream.
Pour into quart size freezer bag. Freeze flat.
Cooking - Oven Option
To cook the meatballs from frozen, pop them in the oven in a pan or baking sheet for 30 minutes in a 400F oven.
While meatballs are cooking, run sauce bag under warm water to loosen. Dump sauce mixture (with the exception of sour cream) on the stove and bring to a simmer.
Mix in sour cream
Once the meatballs are fully cooked, add them to the thickened sauce and season with salt & pepper.
Cooking - Crockpot Option
Add thawed sauce (or fresh sauce ingredients!) to lined crockpot and stir.
Add frozen meatballs, cook on low for 6 hours.
Stir in sour cream just before serving.
