In a bowl, combine warm water, milk, sugar, and dry yeast. Let it sit until bubbly.

Beat in the eggs, then add in the flour, salt, and softened butter. Knead until smooth, cover, and let it rise for about 1 hour.

After the dough has doubled in size, divide it into equal parts and shape into balls.

Arrange on a baking sheet, sprinkle sesame seeds on top if desired, and let rise for another 30 minutes.

Heat a pan with oil. Season the beef with salt and pepper, then form into patties.

Cook on medium heat until they reach your preferred doneness.

While the patties are cooking, slice the bell peppers, pit and slice the olives, and set aside your cheese, pickles, and lettuce.

Preheat the oven to 180°C (350°F) and bake the buns for about 15-20 minutes or until golden brown.

Let them cool before slicing.

Layer the bottom bun with lettuce, a beef patty, cheese, bell pepper, green olives, and a dash of ketchup.

Top off with the upper bun.

A side of crispy fries is the perfect companion to your beautifully assembled burgers.
