Heat a gas grill to high heat. Place the pineapple rings on a grilling mesh and grill for 10 minutes until golden brown on the bottom. Cool the pineapple and cut into small chunks. Combine the pineapple chunks, nopalitos, olive oil, chopped piquillo & jalapeño peppers, jalapeño salsa, salsa verde, chopped tomatoes and chopped bell peppers in a large bowl. Toss the ingredients to combine, cover and refrigerated until ready to use.
