Place halves with skin-side up on a baking sheet and bake on high for approx. 10 min. until skin is completely black. Remove from oven, cover with a slightly wet towel and let cool. Remove black skin from pepper with a knife and discard.
Peel and dice onion and potatoes. Transfer diced onion and potatoes to a pot, cover with water, and cook for approx. 15 min. until tender. While cooking, reserve some cooking water. Strain the mixture and set aside.
Transfer potato-onion mixture, remaining water, and roasted red pepper to a blender. Add cashew nuts, vegetbale, chili pepper, paprika, lemon zest, garlic slice, lemon juice, miso paste, vegan Worcestershire sauce, mustard, salt and pepper. Mix on high for approx. 1 min.
