With your knife, add a few slits into the squash where you intend to slice down the middle.
Place squash on a dish and microwave whole squash for about 5-6 minutes (once it's a little softened it will be easier to slice).
When ready, remove from microwave and slice down the middle.
Remove seeds and sprinkle with olive oil, salt and pepper.
Roast at 400 for about 35 minutes.
Dice onion and chop bell pepper into bite sized pieces.
Heat about 1 tsp olive oil in a saute pan and add veggies. Season with salt.
Saute until softened, about 3 minutes, then add beans and cilantro. Mix together and season again with salt, if needed.
When squash is ready, add bean mixture to the center of squash and top with cheese. You can place squash back in warm oven to melt cheese or microwave for about 45 seconds.
To eat, mix bean and cheese mixture with squash noodles.
