These are Gardein meatballs. They held up very well in sauce. I sautéed them in oil first for about 10 minutes. I set them aside and made the sauce in the same pan: I sautéed onion, then added 1/2 a can of crushed pineapple and about a cup of BBQ sauce and a pinch of crushed pepper flakes. Once it all started simmering, I added the meatballs and simmered for about 15 minutes over medium low heat.
