Spaghetti Squash with Chicken and Summer Pesto

This is a great recipe to use up leftover roast chicken. Or snag a cooked rotisserie chicken from the grocery store and whip this up tonight.

Spaghetti Squash with Chicken and Summer Pesto

One big perk of meal planning is that once you get the hang of it, you find you don’t have to cook every. single. day. For example, this spaghetti squash with chicken recipe.

Bake your squash beforehand – possibly on the weekend, when you have more time. We love to use leftover roast chicken for this recipe or you can also grab a pre-cooked rotisserie bird from the grocery store. And the pesto in this recipe can also be made ahead of time (or cheat even better and buy a good premade one at the store!)

If you opt to make your own summer pesto, drizzle olive oil over the top and cover to keep the pesto green. It will be good for a few weeks in the fridge (if it lasts that long!) or you can freeze it.
