Bring two cups of water to a boil with the Better Than Bouillon base. Add the rice and cook until it is almost done. Set it aside to cool.
Heat the olive oil in a large skillet. Add the onion and sauté until it is golden. Add the grated carrots and cook until they are soft.
In a large bowl, combine the sautéed veggies, raw ground meat, cooked rice, salt, and pepper. Mix until everything is evenly combined.
Cut the tops off the mini bell peppers and remove the seeds. Spoon the filling into a large piping bag, then snip off about 1/2 inch from the tip and pipe the mixture into each pepper. Arrange the peppers snugly in a large baking dish.
To make the sauce, heat the olive oil in a skillet or saucepan. Add the diced tomatoes and garlic. Simmer until the tomatoes have softened, about 10 minutes.
Stir in the Better Than Bouillon and hot water, then add the sour cream, salt, and pepper. Mix until the sauce is creamy.
Pour the sauce over the peppers. Cover the baking dish and bake it at 400°F for about 60 minutes, or until the peppers are tender and the filling is fully cooked.
Serve the stuffed peppers with a spoonful of the creamy sauce and a sprinkle of chopped parsley. Enjoy!
