1 slice hearty sandwich bread, such as peasant bread, sourdough, whole-wheat or multi-grain
2 tablespoons plain Greek yogurt
1 teaspoon honey, plus more for drizzling
1/4 teaspoon vanilla extract
1/2 medium avocado
Flaky salt, such as Maldon, for sprinkling
Toast the bread. While the bread is toasting, mix the yogurt, 1 teaspoon honey, and vanilla together.
Spread the yogurt mixture on the bread. Cut the avocado into 1/4-inch-thick slices and lay the slices, overlapping slightly, to completely cover the yogurt. Drizzle with more honey and sprinkle with the salt.
