Lightly toast two slices of bread in a frying pan with olive oil over low heat.
Mix honey, mayonnaise, and whole grain mustard in a 1:1:1 ratio, then add a pinch of black pepper.
Spread the sauce generously on the toasted bread, then place washed and dried lettuce on top.
Slice a boiled egg thinly and lay it over the lettuce.
Clean and slice the tomato, pat dry with a paper towel, and place the slices on top of the egg.
Add one slice each of ham and cheese on top.
Spread sauce on the remaining slice of bread, cover the sandwich, and wrap tightly with plastic wrap.
Cut in half with a knife and enjoy!
