01 - Bring a large pot of salted water to a boil. Add the tortellini and cook for 2 minutes less than the package directions so they remain al dente. Drain and immediately rinse under cold water to halt cooking. Pat thoroughly dry with paper towels.
02 - In a shallow bowl, whisk together the eggs and milk. In a separate shallow bowl, combine the breadcrumbs, Parmesan cheese, garlic powder, dried Italian herbs, salt, and black pepper.
03 - Dip each tortellini into the egg mixture, then roll in the breadcrumb mixture, pressing gently to ensure an even, adherent coating.
04 - To fry: Heat 1 inch of vegetable oil in a deep skillet to 350°F. Fry tortellini in batches for 2 to 3 minutes, turning occasionally, until golden brown and crispy. Remove with a slotted spoon and drain on paper towels. To bake: Preheat oven to 425°F. Arrange breaded tortellini in a single layer on a parchment-lined baking sheet. Spray generously with olive oil spray. Bake 12 to 15 minutes, turning halfway through, until golden and crisp.
05 - Serve warm alongside marinara sauce for dipping.
