To make filling: combine first 8 ingredients (turkey - thyme) in a bowl.
Spoon filling into bell peppers.
***Transfer peppers to freezer container and cover and freeze up to 1 month""".
Preheat oven to 350-degrees F.
Transfer peppers to 9-inch baking dish and pour tomato puree over peppers, adding enough water so liquid comes at least 1/4 up sides of peppers. Cover with foil and cook for 30-40 minutes, basting occasionally or until peppers are tender and filling is cooked (temp of filling should read 165-degrees F using an instant read thermometer inserted into filling).
