Frugal Living. If you are like me, you are frugal when it comes to the family food budget.
If you have fresh garden tomatoes, making a spaghetti sauce would be a great option.
Tastes so good. It is very hard to waste food when I think about all that goes into everything we eat; from the farms to our family. Therefore, when I had spaghetti in the refrigerator for four days, I wanted to make something new with it so my family would use it up.
Leftover Spaghetti is Now Simple Baked Spaghetti
Even to make the simple baked spaghetti, I used what I had in my refrigerator. It was extremely easy because everything was already pre-cooked. All I had to do was layer the ingredients into a casserole dish. Now, that is my kind of meal. I did serve a salad along with the baked spaghetti to round out the meal.
Store Leftovers Separately
I store my leftover cooked spaghetti and spaghetti sauce in separate containers in the refrigerator. It lends itself well to this recipe. My spaghetti sauce was a meat sauce.
New Weeknight Meal from Leftovers
Combine pasta with a spaghetti sauce, cheese, and bake in the oven until bubbly. The gooey cheesy goodness combined with the fresh sauce and the comforting pasta make just a delicious weeknight meal.
