Fire roast poblano peppers over open flame or under broiler until well blackened on all sides. Place in a small bowl and cover for 5 minutes. Run under cool water, rinsing away black pieces. Cut out and discard stems and seeds. Dice.
Heat olive oil in medium cast iron skillet or other sauté pan over medium heat. Add diced poblano, onion and jalapenos. Sauté about 5 minutes; add in diced chorizo and cook another 5-10 minutes until onion is tender.
Add in cheese and stir until melted. Remove from heat and top with scallion, diced tomato and fresh cilantro. Serve with tortilla chips.
