Herbed Tomato Gratin

Preheat oven to 400 degrees F. Coat a 9-by-13-inch pan (or similar-size 3-quart baking dish) with cooking spray.

Heat oil in a large skillet over medium heat. Add bread and cook, stirring occasionally, until brown and crispy, 6 to 8 minutes.

Transfer the bread to a large bowl. Gently stir in cream, 1/4 cup cheese, marjoram, garlic, vinegar, salt and pepper. Spread the mixture in the baking dish. Layer tomatoes on top and sprinkle with the remaining 1/4 cup cheese.

Bake the gratin until golden and crispy on top, 40 to 45 minutes. Garnish with marjoram, if desired.
