Cut poblano chiles in half lengthwise to create boats for filling; scrape out seeds.
In nonstick skillet, heat olive oil.
Add onion, garlic, jalapenos, red bell pepper, cilantro and cumin; cook over medium heat until golden brown, about 4 minutes.
Remove pan from heat and stir in vegetarian baked beans, hot sauce and 8 ounces cheese. Add salt and pepper, to taste.
Spoon mixture into hollowed chiles and sprinkle with remaining cheese.
Preheat grill to medium heat.
Arrange chiles on grill away from heat. Cook until chiles are tender and cheese is browned and bubbling, 30-40 minutes.
Remove from grill and serve.
