4 red or yellow bell peppers, halved lengthwise, seeds and stems removed
2 teaspoons chopped fresh thyme leaves
Heat oven to 400°F. Line cookie sheet with foil.
In 10-inch skillet, cook bacon over medium heat until crispy. Remove bacon from skillet, reserving bacon drippings in skillet. In small bowl, crumble 2 slices of bacon; set aside. In large bowl, crumble 4 slices bacon. Add mustard, tamari soy sauce, salt, cayenne, garlic and egg; mix well. Set aside.
Meanwhile, in food processor fitted with metal blade, place cauliflower. Cover; pulse until very finely chopped (about the size of couscous).
Heat bacon drippings over medium heat; add onion, celery and kale. Cook 3 to 4 minutes, stirring frequently, until kale begins to soften. Add cauliflower; cook 5 to 7 minutes or until cauliflower is softened. Pour mixture into large bowl with bacon mixture; toss lightly to thoroughly mix.
Place pepper halves on cookie sheet. Divide cauliflower mixture among peppers. Roast 25 to 30 minutes or until peppers are tender. Sprinkle with reserved bacon and thyme. Serve immediately.
