Recipe(tried): Portobello Muffuletta (no meat, make ahead)

PORTOBELLO MUFFULETTA

1 (1 lb) round sourdough bread loaf
1 tablespoon red wine vinegar
2 tablespoons olive oil
2 teaspoons Dijon mustard
1/4 teaspoon sugar
1/4 teaspoon salt
1/4 teaspoon freshly ground pepper
6 oz fresh Portobello mushroom caps
1 cup torn romaine lettuce leaves
1/4 cup chopped sun-dried tomatoes in oil, drained
2 oz provolone cheese, sliced
1 medium tomato, sliced
1 small onion, sliced

Slice off the top third of the bread loaf and set aside. Pull out center of bottom portion of bread loaf with your hands, leaving a 1-inch shell around the outer edges and bottom. Set aside hollowed-out bread loaf, and reserve the center for another use, if desired.

Preheat broiler.

In a 1-cup measure or small bowl, combine vinegar, mustard, oil, sugar, salt and pepper, and whisk until smooth. Brush HALF of this mustard mixture evenly over tops of mushrooms.

Broil mushrooms about 4-inches from heat until lightly browned, about 5 minutes.

Brush remaining mustard mixture over inside of hollowed-out bread loaf. Layer lettuce on bottom and up the sides of the loaf. Layer evenly with sun-dried tomatoes, mushrooms, onion, tomato, and cheese.

Broil this portion of the bread until cheese melts on top, about 5 minutes or bake at 400-450 degrees F for 5-10 minutes until cheese melts.

Top filled loaf with reserved top crust, pressing down firmly with hands. Cut into 6 wedges to serve.

TO MAKE AHEAD:
This sandwich packs well for picnics. Wrap tightly in plastic wrap, refrigerate, and slice just before serving.
