Pesto Sauce

Made with fresh basil, olive oil, garlic, and nuts, pesto not only adds incredible flavor but also offers health benefits if consumed in moderation. According to Parul Dube at, here are a few of those:

  • Rich in omega-3s, reducing heart disease and strokes
  • Packed with antioxidants
  • Contains healthy fats
  • Helps lower cholesterol levels

Keep in mind, this is in moderation. Pesto is also high in fat and should be consumed in small amounts.

  • 8 Chicken Tenders cut from 2 chicken breasts
  • 1/3 cup Pesto prepared
  • 4 oz Goat Cheese
  • 1 Spaghetti Squash
  • 1 cup Cherry Tomatoes
  • Garlic Salt or Salt for seasoning optional


  • Preheat oven to 350℉. Season chicken tenders with a sprinkle of garlic salt (optional). Place tenders in a sprayed 9×11 pan, followed by tomatoes and goat cheese. Bake for 20 minutes, or until chicken is at 165℉.
  • While chicken is baking, cook spaghetti squash. Cut in half lengthwise, scoop out seeds, place flesh side down on a plate and microwave for 5 minutes on high. Check squash to see if it is still hard. It should have some give to it and the flesh should shred with a fork. If it is still hard, microwave for another 2-3 minutes. Shred flesh with fork.
  • Remove dish from oven once chicken is at 165℉. Take chicken out and shred or dice into bite size pieces. Add pesto to dish, stirring to create a sauce with the juices in the pan.
  • Add spaghetti squash into dish, stir to coat with sauce. (If you have picky eaters, and are doing pasta for them, keep the squash and pasta separate. Toss each with a little sauce. You may need to add more pesto.) Add in chicken, stir, and enjoy.
