1

Heat gas or charcoal grill. In small bowl, mix mayonnaise spread ingredients. Refrigerate. With small metal spoon, scrape underside of mushroom caps to remove dark gills.
2

Spray mushrooms, bell peppers and onion slices with cooking spray. Place on grill over medium heat. Cover grill; cook 7 to 10 minutes, turning occasionally, until bell peppers and onion are crisp-tender. Remove vegetables from grill; let stand until cool enough to handle.
3

Meanwhile, cut focaccia in half horizontally to form 2 rounds. Spread mayonnaise spread evenly on cut side of bottom half.
4

Slice mushrooms; arrange over mayonnaise spread. Cut bell peppers into thin strips; layer over mushrooms. Separate onion slices into rings; place over peppers. Top with tomato and cheese slices. Cover with top half of focaccia.
5

If desired, wrap sandwich in foil; place on grill. Cook 1 to 2 minutes or until cheese is melted. To serve, cut into 6 wedges.

Havarti melts nicely and adds wonderful creaminess to this grilled sandwich. For a different flavor, try a variety such as dill Havarti.
