Cauliflower Parmesan

3 eggs
3 cups breadcrumbs
1 teaspoon Italian seasoning
Salt & pepper
1 medium head cauliflower, trimmed, cut into ½ inch thick pieces
1/2 cup vegetable oil, for frying 
5 cups tomato or marinara sauce
3 cups shredded mozzarella cheese
1/2 cup shredded Parmesan cheese

1. Heat oven to 400°F. Place eggs and pinch of salt in a bowl and beat. Place breadcrumbs in another bowl or a pie plate. Mix the Italian seasoning into the bread crumbs and add salt and pepper. Dip cauliflower pieces in the eggs, then coat with breadcrumbs. 
2. Add some of the oil to a heavy skillet and heat over medium-high heat. Fry cauliflower in batches, until golden brown on both sides. Add more oil as needed. Drain cauliflower pieces on a paper towel-lined plate.
3. Spoon some of the sauce over the bottom of a 9-by-13-inch baking pan. Scatter half the cauliflower pieces over the sauce. Drizzle some sauce over the cauliflower and sprinkle with half the mozzarella. Layer the rest of the cauliflower pieces over the cheese, spread with remaining sauce, and sprinkle with remaining mozzarella and the Parmesan.
4. Bake about 30 minutes until cheese is golden and sauce is bubbling. Let cool 5 minutes before serving.
