How to make
Preheat the oven to 390°F (200 degrees). Place the peppers in a baking pan lined with baking paper and sprinkle them with olive oil.
Bake them in the oven for about 50 minutes and turn them once in this time frame. Take them out and allow them to cool. Peel them, remove their stems and seeds.
Put the garlic and walnuts in a blender. Blend them several times until the walnuts are blended into bulky pieces.
Add the peppers, paprika, a tablespoon of olive oil, parmesan and blend again until the mixture is smooth. Season the pesto with as much salt as you like.
