Savoury tomato-chive yoghurt toast

We took the viral yoghurt toast recipe—which involves spreading a quick, lightly sweetened yoghurt-egg mixture onto bread and then baking—and gave it a delicious savoury twist. We omitted any sweetener from the yoghurt custard and whisked in grated Parmesan and salt, then spread that combo onto bread and topped with halved grape tomatoes and chives. The result is a crunchy toast with a creamy, cheesy topping that tastes indulgently rich. We like the gentle allium notes of chives, but you could use any herb you like; thyme or oregano would be especially good.
