FOR THE OVEN Adjust rack to middle position and preheat oven to 350 degrees. Remove outer packaging and plastic film. Cover rice on tray* with aluminum foil, leaving stew uncovered. Place on a baking sheet and bake on middle rack for 20 minutes. Carefully remove foil and stir stew (leave the rice, beans, and plantains undisturbed). Return sheet to oven and bake, uncovered, until meal reaches an internal temperature of 165 degrees, 20 minutes more. Let stand for 2 minutes and stir. Divide rice, beans, and plantains between plates and serve beef alongside.
*You read that right: All trays and film are oven-safe and microwave-safe!
This meal is fully cooked when internal temperature reaches 165ยบ.
