A delicious meatless 'burger' for the grill.

Top Review by windywood

I really liked this. The Portobellos are very meaty. I skipped the onion but did everything else the same. Next time I'll used provolone cheese instead of Fontina -- personal preference. Very unusual & satisfying "burger". Thanks for sharing!
