Combine 1 tbsp of the olive oil, tomatoes, and gochugaru in a small skillet over medium heat, breaking the tomatoes up with a spoon or spatula, and cook for about 5 minutes, until the juices have mostly evaporated.
In a food processor or blender, pulse the garlic and nuts together until coarsely chopped.
Add the tomato mixture, bell peppers, and remaining sauce ingredients (including the remaining 3 tablespoons olive oil), and run the machine until the sauce is puréed but not silky-smooth.
