I just bought a fresh pineapple the other day at Safeway. I shredded carrot and zucchini and steamed for 3-4 minutes, pan seared some scallops seasoned with Old Bay and topped with pineapple salsa I made with grilled pineapple, green onion, jalapeno, cilantro, and lime juice.
Grilling pineapple is easy, use med-high heat for 2-3 minutes each side. Use olive oil if you want nice pretty grill marks. Good luck, have fun.
