Chop the squash.
Roast the red bell peppers in the broiler on high until the skin is blistered in all sides.
Put into a container to seal and let steam for 15 minutes, (we used a zip lock bag).
When cool enough to handle peel and remove the charred skins, stems and seeds.
Put the roasted bell peppers into the blender with the anchovies and puree.
Add the tomatoes, salt, pepper and capers then puree into a smooth sauce.
In a large skillet add the butter and olive then heat to medium high.
Add the garlic and sauté for a few minutes then add the squash and cook until it starts to brown on the edges.
Add the pureed sauce, cayenne pepper, basil and more salt and pepper if desired.
Cook the pasta per the directions on the package.
Cook the sauce down until it starts to thicken then serve over pasta and top with cheese.
