To keep my family going all morning, I start with lean ground beef and spices, then sneak some spinach into this protein-packed dish. —Jennifer Fisher, Austin, Texas
Prep: 25 min. Bake 45 min
Preheat oven to 350°. In a large skillet, cook beef with onion powder, 1/2 teaspoon salt, garlic powder, sage and pepper flakes over medium heat 6-8 minutes or until no longer pink, breaking up beef into 3/4-inch crumbles; drain. Stir in spinach. Remove from heat.
Spread potatoes in a greased 13x9-in. baking dish; top with beef mixture. In a large bowl, whisk eggs, ricotta cheese, milk, pepper and remaining salt; pour over top. Sprinkle with cheese. Top with tomatoes.
Bake, uncovered, 45-50 minutes or until a knife inserted near the center comes out clean. Let stand 5-10 minutes before serving. Yield: 12 servings.
