Use regular uncooked long-grain white rice; instant and brown rice need different timings and liquid ratios.
The foil should fit tightly so steam can cook the rice. Avoid opening the dish frequently.
Ground beef meatballs must reach 160°F. If using ground turkey, cook to 165°F.
Soup and broth vary in saltiness, so taste the finished sauce before adding salt.
Leftovers keep 3 to 4 days in the refrigerator; reheat to 165°F.
