Preheat broiler.
Cut bell peppers in half lengthwise. Remove and discard seeds and membranes. Place pepper halves, skin sides up, on a foil-lined baking sheet. Broil 15 minutes or until blackened. Place pepper halves in a zip-top plastic bag; seal. Let stand for 15 minutes. Peel and chop peppers. Well worth it I promise!
Heat a Dutch oven over medium-low heat. Add oil to pan; swirl to coat. Add onion; cook for 10 minutes, stirring occasionally. NOTE: If you are using meat-add now; season with salt and pepper (or any other seasonings you like) and cook for about 10 mins or so until cooked through.
Add now the 1 tbsp of tomato paste and chili pepper. Stir until well combined.
Next stir in sugar and the next 5 ingredients (through garlic); cook for 2 minutes, stirring frequently. Next add the beer- to let all the magic happen! (Cook for about 6-8 min until reduced by half.)
Now add bell peppers, broth, squash (if using), and tomatoes (crush the tomatoes with your hands is best); bring to a simmer. Cook for 20 minutes, stirring occasionally. Add beans; simmer for about 20-25 minutes or until slightly thick, stirring occasionally.
Serve in a bowl with the Toppings- All Optional; Sprinkle with cheese, sour cream, green onions, or hot sauce. Add a fresh green salad or a favorite veggie mix. Enjoy! Plus, get ready for the best left overs ever!
