Step 1 Whisk eggs and pepper in medium bowl. Set aside.
Step 2 Combine onion, garlic, bean sprouts, and red and green peppers.
Step 3 Heat 1 tsp (5 mL) oil in 10-inch (25 cm) non-stick skillet over high heat. Add half of vegetable mixture. Cook, stirring, for 1 minute. Sprinkle 1 tsp (5 mL) soy sauce over vegetables and cook for 1/2 minute longer. Reduce heat to medium.
Step 4 Pour half of egg mixture (about 1/2 cup/125 mL) over vegetables in skillet. As eggs set around edge of skillet, with spatula, gently lift cooked portions to allow uncooked egg to flow underneath. Cook until bottom and top are set.
Step 5 Remove crepe from skillet and cut in half. Fold each half and place on bottom half of bagel; cover with top half of bagel.
Step 6 Repeat with remaining ingredients to make two more sandwiches. Serve hot or at room temperature.
