In a large mixing bowl, combine ground meat, cream cheese, cheddar cheese, and diced jalapeños. Add breadcrumbs, an egg, garlic powder, onion powder, salt, and pepper to the mixture. Mix everything thoroughly.

Place a large skillet over medium heat and add a drizzle of olive oil, warm for 2-3 minutes until shimmering.

Take small portions of the meat mixture and roll them into 1-inch meatballs. Arrange the meatballs in the preheated skillet.

Cook the meatballs for approximately 10-12 minutes, turning occasionally to ensure even browning and reaching an internal temperature of 165°F.

Remove the meatballs from the skillet and let them cool for a few minutes on a plate lined with paper towels before serving.
