Place the pepitas/sunflower seeds, roasted peppers, garlic, paprika, tomato paste, parsley, apple cider vinegar, sea salt, and pepper in the bowl of a food processor. Pulse the ingredients together until they form a thick paste. With the machine running on low, slowly drizzle the olive oil into the bowl of the food processor until everything is evenly combined. Taste and add more salt and pepper as needed. Spoon the sauce into a container.
