Prosciutto and Cheese Tartine
Although the name tartine often refers to a French open-faced sandwich, this version is closer to Italian focaccia topped with piquant salad. Because it's inexpensive to make your own flatbread, you can splurge on real Italian Parmigiano-Reggiano, which makes a huge difference in a simple recipe like this one. You'll also have room in the budget for 2 ounces thinly sliced prosciutto for a salty, savory note.
