Cheese Flatbread with Garlic Butter Spread

Dissolve the yeast and sugar in warm milk, and let it sit in a warm place until a foamy cap forms. Sift the flour into a bowl, add the salt, the yeast mixture, and the oil. Knead into a soft dough that doesn't stick to your hands. Form into a ball, place on a parchment-lined baking sheet, cover with plastic wrap, and let it rise.

For the spread, mix the butter, garlic, and egg yolk. Add chopped herbs to taste.

Punch down the dough and roll it out into a circle. Make cuts with a knife, brush on the spread, and place pieces of cheese into the indentations. Let the flatbread rest under plastic wrap for 15 minutes.
