Trim Healthy Mama S Mexican Spaghetti Squash Casserole

A friend gave me some spaghetti squash from her garden. I didn’t know what I was going to do with it but I love the flavors of Tex-Mex, so that’s the direction I went. This is pretty quick and easy. I cooked my spaghetti squash in my instant pot. This recipe has cauliflower rice and minced mushrooms hidden in it. You can probably make this without any pasta, it is full of lots of vitamins and nutrients.

Because most of my family doesn’t like spaghetti squash, I used 2 small squashes to make the casserole and boiled some pasta for them. I split the meat mixture in half and half went with the spaghetti squash and the other half to the regular pasta. They absolutely loved their version. I think they would eat this on a regular rotation. I hope your family likes this as much as mine did.
