To prepare a whole30 squashgetti and meatballs recipe, you'll first need to prepare the squash. Squash can be found at your local grocery store, or you can buy it online. You can also use frozen squash if you don't want to cook it yourself. To make your own squash, mix together 1 cup of water, 2 tablespoons of olive oil, 1 teaspoon of salt, and 1 tablespoon of thyme. Heat the oil over medium-high heat until it's shimmering. Add the garlic and cook until fragrant, about 1 minute. Stir in the tomato paste, then add the ground beef. Cook, stirring occasionally, until the meat is no longer pink, 3 to 4 minutes. Remove from the heat and set aside.
