Cut peppers in half length ways and remove seeds. Place on a lined baking tray and sprinkle olive oil then with garlic and onion powder. Roast for approx 15mins turning every few minutes to make sure they don’t burn.

When cooked, remove from heat.

In a small bowl combine remaining oil, paprika, lemon juice, sea salt, chopped parsley and toasted walnuts. Add the grilled peppers and mix thoroughly. 

Remove peppers and place on a serving platter and top with the rest of the oil mixture.
