Preheat oven to 375 degrees F. Cut squash in half and scoop out the seeds with a spoon. Lay skin side down on a rimmed baking sheet, lined with unbleached parchment paper, and sprinkle with salt and pepper. Bake for 45 mins or until cooked to a touch with a fork.
In the meanwhile, preheat medium skillet on medium heat and spray with cooking spray. Add onion, garlic, bell pepper and saute for 4 – 5 minutes or until golden brown, stirring occasionally. Add beans, chili powder, chilis/jalapeños, tomato sauce, cilantro and stir. Remove from heat and add 1/2 cup cheese. Stir again.
Remove baked spaghetti squash from the oven and let cool a few minutes. Fluff each squash “boat” with a fork releasing some of the strands, leaving the squash in a shell. Fill each “boat” with heaping 3/4 – 1 cup prepared bean/pepper etc. mixture and sprinkle with 1/4 cup cheese each. Bake for additional 10 minutes or until cheese is melted. Serve hot, garnished with extra cilantro.
