Step 1

In bowl, whisk together mustard, honey, marjoram, miso, and pepper. Adjust oven rack 5 inches from broiler element and heat broiler. Place tomatoes in 10-inch broiler-safe skillet and broil until most tomatoes have burst and a few are lightly charred, 8 to 10 minutes.

Step 2

Transfer tomatoes to mustard mixture and toss until tomatoes are well coated. Arrange bread on rimmed baking sheet and broil until golden brown, about 2 minutes per side. Let bread cool until warm to touch, about 3 minutes. Spread ¼ cup ricotta on each slice of bread. Top with tomato mixture. Serve.
