How to make it
1
Remove the Factor sleeve and peel back the film partway to vent. Microwave on HIGH for 2 minutes. Let stand 1 minute, then carefully remove the film — the tray will be hot. Factor meals are chef-crafted and fully cooked; heat poultry and pork to 165°F, beef to 160°F, and fish to 145°F internally.
2
Oven method: Preheat to 325°F. Remove the sleeve and film entirely. Place the tray on an oven-safe baking sheet and heat for 20-25 minutes until steaming throughout and reaching the appropriate internal temperature. The oven method is ideal for Factor's protein-forward entrées — it preserves texture better than microwave for steak and salmon.
