Heat the oven to 375°.
Lightly grease a 9x13" baking dish.
Heat 2 tablespoons olive or avocado oil to the large skillet over medium heat. Add the sausage, onion, garlic, one teaspoon salt and 1/2 teaspoon pepper. Cook, stirring occasionally, until the sausage is browned and cooked through, about 8-10 minutes.
Create a space in the middle of the pan and add the tomato paste. Let it cook, stirring frequently in the center of the pan, until darker in color, about 2-3 minutes. Then stir the paste into the sausage and onions.
Add the riced cauliflower and cook, stirring occasionally, until warmed through, about 3-5 minutes.
Stir in the chopped olives and parsley. Take the pan off the heat.
Slice approx. ½" off the top of each pepper. Discard the stems but if you can save the rest of the pepper "lid," store it in the fridge for up to 5 days for another use. Arrange the peppers in the greased baking dish. If any peppers don't stand up, cut off a very thin slice from the bottom of the pepper (not enough to create a hole).Sprinkle the inside of each pepper with a bit of salt. In a small bowl, whisk the eggs. Stir the eggs into the sausage and vegetable mixture.
Use a large spoon to fill the peppers with the meat mixture all the way to the top. Gently pat to create a flat layer.
Add a large handful of crackers to a plastic baggie but don't seal the bag. Use a rolling pin or meat hammer to crush the crackers into fairly fine crumbs .It doesn't have to be a powder - you just don't want too many large chunks.
Measure out ⅓ cup of the cracker crumbs and add to a small bowl. Stir in the 2 teaspoons olive or avocado oil until all the crumbs are evenly coated. Spoon about one tablespoon of the cracker mixture onto each pepper, gently pressing them down into a flat layer.
Bake the peppers for 30 minutes, or until the peppers are tender. Let cool for 5 minutes, then dig in!
