Beef Enchiladas & Enchilada Sauce

I've been trying to find an enchilada recipe that the whole family will eat for a long time. Finally found one!

Enchilada sauce
1 Tbsp olive oil
1 small onion, diced
3 cloves garlic, minced
3 Tbsp chili powder
1 Tbsp cumin
1 tsp salt
1/4 tsp oregano
1 15oz can tomato sauce
1 cup chicken stock

1. Heat oil in a medium saucepan over medium-high heat. Add diced onion and cook until just browned, about 5 minutes. Stir in garlic, chili powder, cumin, salt and oregano and cook for about 30 seconds, stirring constantly. Sauteing your spices for a few seconds will give your sauce a fuller flavor.
2. Add in the tomato sauce and chicken stock. Bring mixture to a simmer and cook for approximately 8 to 10 minutes, stirring occasionally.
3. Remove from heat, and strain mixture through a fine mesh strainer, pressing on the onion to extract the sauce. If I am making enchiladas or something similar, I'll add the reserved onions to my filling. You may discard the onion if you wish.
4. Keep refrigerated for up to one week. Makes approximately 2 cups.

For the enchiladas, just brown 1 lb ground beef. I added some taco seasoning to it while cooking. Once it was cooked I added in the leftover onion and garlic from the enchilada sauce......plus a little bit of the sauce! When forming the enchiladas I added a little bit of shredded cheese. Then once all of the enchiladas were in the pan I poured the sauce over them. Bake @ 350 for about 15 minutes or until cheese is melted.
