Ideas for how to use up homemade tomato sauce, that don't involve pasta?

I made some tomato sauce over the weekend to serve over some baked chicken, and I've found myself with a lot leftover. It's kinda basic, with garlic, mushrooms, carrots, and celery. I've already used up some of it by mixing it with ground sausage for stuffed peppers, and I was hoping for more ideas to try and get 1-2 more meals out of it. I'd also like ideas that don't involve pasta, since that feels a little too obvious and I want to be a bit more creative if I can.
