Begin with toasting the bread, assemble the sandwich as follows; spread on the mayonnaise and grainy mustard if desired, next add the arugula leaves to all of the slices of toast.
Add the cooked bacon strips to each slice of toast, ( I break mine in half). Next add a slice of tomato, 2 or 3 slices of the avocado and hard boiled egg to just 2 of them. Sprinkle with the chopped chives.
Fold the sides together and slice in half, place on a plate and add a side of your favorite grapes for a tasty lunch.
