Quinoa and Spaghetti Squash Casserole

What a week!

It started out with me and the kids having colds. Then my youngest’s “giant boo boo” got infected and he started antibiotics… which resulted in us finding out, the hard way, that he is allergic to penicillin.

Around the time that he broke out in head-to-toe hives, he also caught a virus. A little later in the week, we found out that my oldest has 20/70 vision and astigmatisms. On top of all of that, I injured my leg (the doctor suspects a stress fracture) and caught the dreaded virus that Max is suffering through.

Since Rahn is the only one not diagnosed with something this week, I have warned him to watch out for wild bears in the backyard or random meteorites falling to earth.

Unfortunately, while dealing with pain, hives and tantrums over wearing glasses, we still have to do laundry, buy groceries, and get dinner on the table.

When weeks like this happen, a good casserole is always a great dinner choice. Casseroles are easy to make and are usually make great leftovers.

One of my family’s favorite casseroles came into existence when we were craving lasagna, but didn’t have any pasta. We substituted spaghetti squash and quinoa instead.


Give it a try! I think you’ll like it. Oh, and there is no need to wait until your family is experiencing blurred vision, broken bones or potentially life-threatening allergic reactions to make this for your dinner table.

      We used a 14.5 oz can of diced tomatoes, and a 24 oz can of spaghetti sauce. Those amounts are good starting points, but you can definitely add a little more or little less depending on your personal taste.

      I hope you enjoy it. It is one of our family favorites.
