Pressure Cooker Spaghetti Squash with Pesto

READY IN: 25mins
Recipe by TishT

Select a medium sized squash that will fit into the pressure cooker even when cut in half. If the squash is larger, simply cook it in two batches. I have easily converted this recipe to oven with the same results

Yum. I had already started baking the squash in 1/2 an inch of water at 350 when I found this recipe. I wanted to find out if anyone else thought spaghetti squash would be good with pesto, and this gave me the confidence to try it. I added grated jack cheese to the top, and my hubby and I were both soo delighted. I want more, but have to save it for my son when he comes home. I could eat a whole spaghettin squash this way. I will definitely do this again.
