Place the scallops in a shallow dish and sprinkle with the olive oil, red pepper flakes, salt and pepper. Cover and let marinate for at least 30 minutes.

To make the pesto, put the nuts, mint, garlic, and scallions in a mini food processor or blender and blend coarsely. Add the oil and puree until fairly smooth and bright green. Stir in the vinegar and season to taste with salt and pepper. Set aside while you prepare the scallops, or store in a jar in the refrigerator for up to 5 days.

In a large frying pan, over medium heat, cook the zucchini noodles for about 2-3 minutes, tossing occasionally until heated through. Set aside in a bowl. Next, in the same frying pan, sauté red pepper for 1-2 minutes, add the scallop and oil mixture and cook for another 2-3 minutes, or until the scallops are cooked through. Do not overcook the scallops or they will be tough. Add the zucchini noodles back to the pan and toss with half the pesto until well combined. Store the remaining pesto in the fridge for later use.

Evenly distribute the zucchini noodles and scallop mixture on each plate. Sprinkle each serving with lemon juice.
