Wash bell peppers, cut the tops (reserve) and remove seeds. Set aside. In a food processor with the metal dough blade inserted add the carrot, celery, and onion. Pulse until semi finely chopped (do not over pulse, you'll end up with paste). Add ground beef or turkey, chicken bouillion, red pepper flakes, cilantro or mint (I prefer mint) and egg. Pulse until all incorporated. Remove from food processor bowl into a meduim bowl. Hand mix rice into meat and vegetable mixture. Equally divide meat mixure and stuff the bell peppers. Top with ketsup. Place stuffed bell pepper in center of a 9x13 shallow pan (that has been sprayed with non stick spray) on the sides place the caps of the peppers with stem upward. Place in pre-heated 350 degrees and bake for about 40 minutes. Remove from oven. Enjoy
