Paleo & Whole30 Italian Meatballs with Spaghetti Squash

I have a confession to make. Until now, I’ve never tried spaghetti squash. Even with all hype out there about how wonderful it is, I remained skeptical and never tried it. I’ve made oodles of zucchini noodles and even some cauliflower rice once or twice. (See what I did there?) But no spaghetti squash. Man, have I been missing out. Beth at Budget Bytes recently wrote a great post on how to make spaghetti squash in the slow cooker, and I decided to try it. Go there to read her writeup if you want the details on the whole process, and then come back here for the Paleo & Whole30 Italian Meatballs recipe. These Italian meatballs are da bomb (dot com)!

My spaghetti squash was about three pounds. I washed it well, poked it 10-15 times with a fork and cooked it in the slow cooker for about 4 hours until it gave slightly when I pressed on it. You can use two slow cookers at a time to make the spaghetti squash and meatballs (which I did), or you can make the spaghetti squash ahead of time. Make sure to halve your spaghetti squash on the “equator.” You’ll have longer “noodles” that way. Remove the seeds and use a spoon to scoop out the insides once it’s done.

    I am currently on day 26 of my second whole 30. My first was a hit, i stuck with it for 7 months. then i got pregnant and had a baby! Needless to say prego me didnt care about whole 30 just whatever i was craving. But this happened to me as well with the eggs. Its the eggs that have a big negative affect for me and i also had my galbladder removed which means that pork and to rich beef is also a problem in big amounts. So maybe try just eggs 1 time a week and it may help i realized that with whole 30 eggs are in almkst 2/3 of the meals i made and that was the issue. Sad j also love eggs in many ways.
