Stir together pineapple, red pepper, red onion, jalapeño, lime juice, cilantro and salt. Let stand for 10 minutes.
Stir together barbecue sauce and chipotles. Set aside.
Heat vegetable oil in large skillet set over medium heat; cook Quorn Meatless Fillets for 5 to 7 minutes or until golden brown all over. Remove Quorn Meatless Fillets and slice thinly. Return to skillet along with barbecue sauce mixture. Cook for 2 to 3 minutes or until sauce starts to thicken.
Assemble Quorn Meatless Fillets, cabbage, avocado and Pineapple Salsa in warm tortillas. Serve with lime wedges.
Tips: For less spicy tacos, omit chipotles. The salsa is just as delicious with mango or papaya instead of pineapple.
