Saute up some good ol' ground turkey breast in some high quality EVOO.
Stir in lots of toasted flax seed for bulk!
Add a ton of spices and herbs! I LOVE this new freeze-dried stuff! I also added garlic, onions, tumeric, curry, tarragon, thyme, and lots of other doo-dads. I threw in some salt and pepper. Then, after the meat was cooked, I stuffed it all into the peppers, threw on some grated cheddar, and threw it all in the oven at 375 for about, oh, 1 hour or more! Yummy!
