original recipe which makes lots of dishes dirty. Here is my version which only needed one pot.
Ingredient note: I used the canned tomato sauce that you find near the diced tomatoes and tomato paste, not spaghetti sauce or marinara sauce.
For prepping ahead, I pre-boiled the pasta in the morning and mixed in the sauce ingredients. By the time I put it on the stove to reheat that evening, the pasta had totally absorbed the sauce and only needed a few minutes on medium-low to get warm throughout (rather than the 20 minutes of extra cooking given in the OR).
I froze leftovers in individual serving sizes and reheated them for lunch. I recommend reheating in the microwave rather than the stovetop, but if you do reheat on the stove, add a splash of water to the frozen lump of pasta and heat with a cover on the pot to help keep things from sticking to the bottom too badly.
