Bacon, Cheddar, Spinach And Tomato Strata

• butter for pan
• 6 ounces day old bread, cut into cubes
• 4 ounces bacon, cut into small pieces
• 1/2 cup finely chopped onion
• 3 plum tomatoes, peeled, seeded and chopped into small pieces (canned tomatoes are OK)
• 1 cup (ish) baby spinach, roughly chopped
• 6 ounces extra sharp cheddar cheese (use your favorite), grated
• 4 large eggs
• 1 cup whole milk
• 1 tablespoon Dijon mustard (mustard haters can leave this out)
• 1/2 teaspoon fresh ground black pepper
• salt to taste (depends on how salty your bacon is)

1. Butter an 8 inch square baking dish (or one of equivalent size).
2. Cook bacon in a large skillet over medium heat until the fat is rendered and the bacon is crisp. Drain the bacon on a plate lined with paper towels.
3. Pour off all but 1 tablespoon of bacon fat. Saute the onions in the bacon fat until they begin to soften and become translucent, about 3-5 minutes. Add the tomatoes, raise the heat, and cook the onions and bacon together, scraping up any browned bits, until they are somewhat caramelized and any liquid has evaporated. Stir in the spinach till wilted. Remove from heat.
4. Place half of bread in baking dish. Top with half the tomato-onion-spinach mixture and top that with half the bacon, and 1/3 of the cheese. Layer on the rest of the bread followed by tomato-onion-spinach mixture and 1/2 of the remaining cheese.
5. Whisk together milk, eggs and mustard in a large bowl and pour evenly over strata. Sprinkle remaining cheese over top, and grind about 1/2 teaspoon of black pepper over the cheese. Chill strata, covered with foil at least 1 hour and up to overnight (for bread to absorb custard).
6. In the morning, remove strata from refrigerator and heat oven to 350. Bake uncovered 40-45 minutes until cooked through and lightly browned on top. Let rest about 5 minutes before serving.
