Peel and slice carrots, cucumber, and mango; use food cutters to make fun shapes if desired. Set all aside separately.

Whisk 1 egg and 1 tablespoon milk in a small microwave-safe bowl, then cook in the microwave for approximately 30-45 seconds until set (the cooking time will vary with each microwave). Repeat with remaining eggs.

Toast English muffins.

Add an egg to each muffin, forming sandwiches.

Serve each sandwich alongside sliced veggies and mango.
