Pasta shells stuffed with cheese and spaghetti squash

Today on the Hard Scrabble Gourmet we're making pasta shells stuffed with cheese and spaghetti squash. It's a large make ahead recipe that you can freeze for multiple quick week day meals. You'll need sauce for the shells so I'm including my super simple, super cheap, super fast Marinara recipe. Ditch the jar with the added sugar once and for all!

Ben's basic Marinara

Ingredients:
2-3 Tbs olive oil
2-3 cloves garlic minced
1 pinch red pepper flakes
1 tsp dried oregano
2 14oz cans tomatoes, crushed or diced(or one of each)

Heat oil on medium high in a large skillet. Add garlic and pepper flakes and saute until garlic begins to turn brown. Add tomatoes and oregano and allow to come to slow bubble. Reduce heat to medium and cook for fifteen more minutes. Your done! See, wasn't that easy? Makes enough to sauce 1 lb of pasta.
