Place peppers on a broiler pan and blacken the skins of the poblanos all over (leave oven door slightly ajar to allow steam to escape). Place blackened peppers in a bowl and cover tightly with plastic wrap. Cool to handle. Peel and seed peppers, and chop them.
Bring a large pot of water to a boil for pasta.
Heat a heavy pot over medium-high heat with EVOO, a couple turns of the pan. Add onions and garlic, and soften 5 minutes. Add chopped poblanos and pintos to the pot, season with salt, pepper, cumin, coriander, paprika, chili powder and stir to combine. Add tomato paste, stir to incorporate then add beer or stock and tomatoes. Reduce heat to simmer.
