portobello and basil burgers

The skies parted, the snow cleared and just for an instant our family was transported from the frozen tundra into a little piece of heaven... Then Jon proclaimed, "This is the best sandwich I can remember having."

Portobello and Basil Burgers
Adapted from Pioneer Woman

Ingredients
½ cups Light Mayonnaise
16 whole Basil Leaves
4 whole Large Portobello Mushrooms
Olive Oil For Brushing
Salt And Pepper, to taste
4 slices Provolone Cheese
4 whole Light Buns, Split

Instructions
Rinse mushrooms thoroughly.
Combine mayonnaise and basil in a food processor or blender. Pulse until basil is totally mixed in with the mayonnaise. Set aside.
Grill mushrooms in a grill pan or on a charcoal grill, brushing lightly with olive oil and sprinkling with salt and pepper. Melt provolone cheese over the mushrooms.
Drizzle griddle with olive oil. Toast buns over medium-low heat until very crispy and toasted.
Spread basil mayonnaise generously on both the top and bottom halves of the kaiser roll. Place provolone topped mushroom on the bun. Press lightly so some of the juices from the mushrooms will run into the bottom half of the roll.
Serve immediately. Yum!
