Pre-heat oven to 300 degrees.
Wash, dry, and remove the seeds of the bell peppers. Cut in half and place them pulp side down on a cookie sheet. Brush with olive oil and bake for 60 minutes until soft.
Marinate the scallops in the lemon juice and 1 tablespoon olive oil for 45 minutes.
If using fresh mango, peel and cube into large rectangles.
Prepare the hot grill.
Alternate the scallops and the mango pieces on 4 skewers. Reserve the marinade. Place the skewers on high heat for about 6 minutes, turning every 2 minutes and basting with the marinade.
Place the roasted peppers along with the skin, remaining olive oil in a food processor. Pulse for 60 seconds or until smooth.
