Acorn squash stuffed with quinoa and chunky pesto

I call it "chunky pesto" because I tried to make a small batch of it in my large food processor--it didn't quite incorporate all the way. So I mixed a little of it in with the quinoa. Regular pesto would work just fine.

1 acorn squash, roasted
1 cup cooked quinoa, mixed with 1/4 cup pesto
1/2 red pepper, diced
Salt and pepper to taste

That's it! Mix the quinoa with the pesto and red pepper, and mound on top of the roasted squash. There. Done.
