Fill a saucepan a quarter of the way and place eggs in a single layer on the bottom of the pan. Make sure eggs are covered by at least 1-2 inches of water.
Bring to a boil over high heat. Turn off the pan, cover and keep on the burner for 10-12 minutes.
Strain the water from the pan and run cold water over the eggs in the pan to stop the cooking.
Crack and peel the eggs (running under cold water while removing the shell can help it loosen).
Chop hard boiled eggs. Add chopped eggs to a mixing bowl.
Add in mayo, yellow mustard, paprika, onion powder and a pinch of salt and pepper (to taste). Stir well until egg salad is thoroughly combined.
Spread egg salad onto 4 slices of white bread. Top with second slice of white bread. Cut egg salad sandwiches on the diagonal and serve!
