Preheat the oven to 425F.
Remove the top of the peppers, and the core. Cut 3-4 sections and place on a lined baking sheet.
Brush a little oil and sprinkle some salt.
Bake for 45-50 minutes at 425 F.
Remove from oven and cover with a lid for a few minutes. This will help removing the skin.
Remove the skins, and set aside.
In a blender or food processor, add the roasted red or orange peppers, the rinsed white beans, olive oil, walnuts, sweetener, cumin, chili, garlic powder, salt and breadcrumbs.
Pulse until all the ingredients are blended. Taste and season.
