I had frozen a portion of arrabiata sauce from a dinner a couple of weeks ago. It was not enough for our dinner but it was a good base to start from. There were already onions, garlic, and mushrooms in it. I added a can of Rotel (spicy tomatoes with chiles) and the rest of a bag of kale I had. It turned out really well. Not only was it delicious but all the vegetable additions made a really hearty portion, Yay! for a giant bowl of food (GBOF)!

Note: For a vegan/vegetarian preparation omit parmesan cheese.
