I put both on the grill, along with some sliced pineapple...yum.
As far as cook times go, I'd say the squash/potatoes needed about 25 minutes, salmon 15 minutes, and pineapple 5 minutes each side. I kept the grill on low-medium.
I'm happy my grill, and dining al fresco, are back in full force. I've missed them both.
