Preheat the broiler.
Arrange the bread slices in a single layer on a baking sheet. Broil 2 minutes or until the tops are toasted. Remove from the oven. Turn the slices over; set aside on baking sheet.
Combine the egg substitute, basil, milk, salt, pepper, and egg, stirring with a whisk.
Heat a large nonstick skillet over medium-high heat. Add the garlic and pancetta; saut� 3 minutes or until the pancetta begins to crisp. Add the egg mixture to the pan; cook 2 minutes or just until set, stirring gently.
Divide the egg mixture evenly over the bread slices. Top the egg mixture with the tomatoes, and sprinkle with the cheese. Broil 2 minutes or until the cheese melts and begins to brown. Serve immediately.
