Do not overcook the lentils before baking or they will turn mushy in the oven. Cook them until just tender and they will hold up beautifully. The lentil filling can be made up to 2 days ahead and stored in the refrigerator. Store leftover stuffed peppers in an airtight container in the refrigerator for up to 4 days. To freeze, cool completely and freeze in a single layer before transferring to a freezer bag for up to 3 months. Reheat in a 350°F oven covered with foil for 15 minutes until warmed through.
