    This is sooooooooo delicious. I’ve never roasted vegetables before and don’t make a lot of sauces and found it fairly easy. There are 3 different parts though, the squash, the roasted veggies and the sauce, so it took a bit of time, but you can easily do each part while the others are roasting. Next time will be faster as now I know what to do.

      Also, I ended up taking the spaghetti squash out and putting it a baking dish with a 1/4 inch of water. The olive oil was burning. I thought that might happen, not sure if I did something wrong.

      …..and…this is so creamy (but there’s no cream or cheese) it fooled my dog. She loved it!
