Cheese-Filled Meatballs with Sauce

Warm the oil in a large saucepan over medium-high heat. Add the onion, lower the heat to medium, and cook for 8 to 10 minutes, stirring frequently until the onion is soft.

Incorporate the remaining sauce ingredients, bring to a boil, then lower the heat to simmer for 25 to 30 minutes until it thickens. Adjust the seasoning as needed.

Set the oven to 375 degrees. Cover a baking sheet with nonstick aluminum foil or parchment paper and apply cooking spray.

In a bowl, mix together the egg, milk, oregano, cumin, salt, pepper, garlic, and panko thoroughly.

Add the ground beef and mix thoroughly.

Shape the mixture into 24 meatballs, each 1 1/2 inches in size.

Insert a cheese cube into the center of each meatball, ensuring the cheese is well enclosed.

Arrange the meatballs on the prepared baking sheet. Bake for 15 minutes or until the center reaches 165 degrees.

Serve the meatballs with the sauce over rice or pasta.
