Cook time 5 minutes
Heat a small skillet over medium heat and add a butter or olive oil. In a small bowl, beat the egg and milk together with a fork until well combined. Season to taste to salt and pepper.
Add the egg mixture to the skillet and turn heat to low. Using a heat-safe spatula or wooden spoon, move the egg around the pan until set and cooked through.
Add the eggs to the toast and top with arugula, cheddar cheese and salsa.
