Raw breakfast sausage, baking mix, cheese and well-drained tomatoes form these oven-baked sausage balls. Drain the tomato-chili mixture before measuring it into the bowl and keep the portions small and even. Check the meat temperature rather than assuming a browned cheese surface means the centers are ready. Drain the tomatoes well before measuring them into the sausage mixture; excess can liquid makes the balls difficult to shape. The breakfast sausage goes into this mixture raw, so cheese melting is not a doneness test. Make similar one-inch portions and leave space between them. Check the center of several pieces: pork or beef sausage needs 160°F, while poultry sausage needs 165°F. If the outside darkens too quickly, check oven placement and use a lower rack next time rather than serving undercooked centers. Keep uncooked portions refrigerated while the first tray bakes.
