Argentinian Cheeseburger Sandwich

Source: Just Recipes

1/3 lb Charcoal grilled or fried-hamburger pattie
1 sl Cooked ham
1 Hard-fried egg (yolk is not-soft)
1 sl Mozzarella cheese
1 Bakery-style sandwich bun
Butter

(The following is for one sandwich, adjust according to your needs)

Lightly toast the bun and spread with butter. Place the hamburger
pattie on the bottom section of bun, add the ham, then the egg and
finally the cheese. Broil only until cheese has melted. Top with
remaining bun. Serve immediately with preferred condiments.

Though we didn't think of it at the time, this would be great with
slices of garden fresh tomatoes.
