SPINACH, MUSHROOM AND CHEESE BREAKFAST CASSEROLE

Steps:

• Grease a 9-by-13-inch (3-quart) casserole dish with oil.

Add the garlic, thyme, 1/4 teaspoon salt and some pepper, stir continuously for 1 minute, then fold in the spinach and another 1/4 teaspoon salt. Continue to cook, stirring often, until the spinach is wilted, 1 to 2 minutes. Remove from the heat.
• Place half the bread cubes in the prepared casserole dish, and sprinkle them with half each of the Gruyere and Parmesan. Add the mushroom-spinach mixture in an even layer. Top with the remaining bread cubes, Gruyere and Parmesan.
