Pre-cook bacon. Don't overcook bacon, leave it limp. Cut the bacon in half so the strips are half as long. Cut walleye fillets into 1.5" square bite size pieces. Wrap the walleye pieces each with a piece of bacon, insert a toothpick to hold in place. Heat grill to med/low and lay a piece of tin-foil down. Place the bacon wrapped walleye on the tin-foil to cook, flipping them once. when done put a dap of BBQ sauce on them. Enjoy.
