For the Meatballs:
 8 oz 80/20 ground sirloin
 4 oz Italian sausage, casings removed
 ¼ small yellow onion, chopped
 1 tsp garlic powder
 1 tsp sSalt
 2 tbsp unsalted butter, for the pan
For the "Spaghetti":
 2 tbsp unsalted butter
 2 cups small zucchini, spiral-sliced into noodles
 2 cups yellow squash, spiral-sliced into noodles
 1 orange bell pepper, cut into strips
 1 small tomato, diced
 black pepper
For the Sauce:
 ¼ cup half-and-half
 1 medium avocado, mashed
 ¼ cup Parmesan cheese, grated

Preheat the oven to 300°F.


Make the meatballs: In a large bowl, mix together the ground sirloin, sausage, onion, garlic powder, and salt until well combined. Divide the mixture into twelve 1-ounce meatballs. In a large sauté pan over medium heat, heat 2 tablespoons of butter for 1 to 2 minutes. Add the meatballs and sear for 1 to 2 minutes on each side, then remove them to a sheet pan. Place in the oven to finish cooking, 4 to 7 minutes.


Make the keto “spaghetti”: In the same sauté pan you used to cook the meatballs, heat 2 tablespoons of butter over medium heat. Add the zucchini and squash noodles, bell pepper, and tomato and sauté for 3 to 4 minutes. Reduce the heat to low and simmer until the noodles and bell pepper are tender, about 5 minutes. Season to taste with salt and pepper.


While the meatballs are cooking and the noodles are simmering, make the sauce: Place the half-and-half in a microwave-safe bowl and microwave for 1 to 2 minutes. Add the mashed avocado to the heated half-and-half and whisk until smooth. Season to taste with salt and pepper.


Divide the noodles and vegetables among 4 plates, then top each plate with 3 meatballs. Spoon the avocado sauce over the meatballs and garnish with Parmesan; serve your keto spaghetti immediately.


Store your leftover keto spaghetti in an airtight container in the refrigerator for up to 6 days.
