Here's what I did:
Buffalo/Chorizo Sloppy Joe
1 lb ground buffalo
1 lb Mexican Chorizo sausage
2 Anaheim peppers
1 red bell pepper
1 small onion, diced
4 cloves garlic, minced
6 oz can tomato paste
2 cups water
1/2 Tbsp cayenne pepper
1/2 Tbsp cumin
1 Tbsp turbinado (raw) sugar
Char the peppers over a hot grill, burner, or broiler a few minutes a side. Remove when charred and blistered, resting in a zip lock bag for 5 minutes. Peel the charred skin, slice open and de-seed the peppers. Dice.
Preheat a dutch oven over medium heat on the grill. Brown the ground buffalo and chorizo, then remove and drain.
Add the onions to the dutch oven with 1 Tbsp of the reserved meat drippings and saute for 5-7 minutes until softened. Add the garlic and cook 1-2 minutes longer.
Return the meat mixture to the dutch oven. Add the roasted chili peppers. Mix the water, tomato paste, pepper, cumin, and sugar together and then add to the dutch oven. Once this comes to a simmer, cover and kill the grill heat (shut the vents or gas).
After 5 minutes, stir, season with salt and pepper to taste and remove to rest (covered) for another 5 minutes.
