Put the onion, bell peppers, chipotle peppers, red pepper sauce, and tomato paste in the bowl of a food processor. Process until you have a nice paste. Set aside.

If you are using a stand mixer put the meat, breadcrumbs, wheat germ and Worcestershire sauce in the bowl of your mixer. Mix these ingredients on low speed just until combined, then add the mixture in the food processor and mix that on low until all is combined.

If you are using a regular bowl, mix it all together, but do not handle it too much or the meat will toughen.

Roast the meatloaf at 350F/177C for 45 minutes or until an instant-read thermometer reads 130F/54C.

Paint the top of the loaf with ketchup or your favorite barbecue sauce and roast for another 10 to 15 minutes. Let the loaf rest at least 10 minutes before cutting.
