This squash is outstanding as a side dish, but you can also top it with canned tuna to create a simple, healthy main dish. It's easy and so tasty! I like to use my own canned tomatoes for the best flavor. —Carol Chase, Sioux City, Iowa

  • 1 medium spaghetti squash (about 4 pounds), halved, seeds removed
  • 1/4 cup sliced green olives with pimientos, drained
  • 1 can (14 ounces) diced tomatoes
  • 1 teaspoon dried oregano
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 1/2 cup shredded cheddar cheese
  • 1/4 cup chopped fresh basil


  1. Place squash in a 6- or 7-quart slow cooker, overlapping as needed to fit. Cook, covered, on low until tender, 5-7 hours.
  2. Remove squash from slow cooker; drain any cooking liquid. Using a fork, separate the squash into strands resembling spaghetti, discarding the skin. Return strands to slow cooker. Stir in the tomatoes, olives, oregano, salt and pepper; cook on low until heated through, about 15 minutes. Top with cheese and basil.

Test Kitchen tips
  • If you like cheesy goodness, top the squash mixture with cheese during the last 15 minutes of cooking, giving it time to get melty.
  • Adding the tomato mixture after cooking the squash allows you to discard any condensed liquid from the slow cooker before combining all the ingredients.
