Core pears and slice into 1/4" slices. Slice onions in 1/4" slices as well and toss with pears, 1 tablespoon olive oil, and 1/4 teaspoon salt. Roast until tender, 15-20 minutes.
Once pears are done, turn on broiler. Brush slices of bread with 1 tablespoon of olive oil and place under broiler for about 1 minute, or until toasted. Remove and top with roasted pears, onions, and gorgonzola. Place back under broiler and toast again for 1-2 minutes or until gorgonzola is browning. Remove, drizzle with honey, and serve.
