- 1 recipe Scallion Oil (optional; see below)
- 1½–2 baguettes, cut into 4 7-inch pieces
- 1–1½ sticks (4–6 ounces) unsalted butter, slightly softened but not greasy
- 6 ounces prosciutto di Parma, prosciutto di San Daniele, or Serrano ham, thinly sliced into about 24 slices
- 1 bunch scallions, green parts only, coarsely chopped (about 1/3 cup)
- 1/3 cup coarsely chopped fresh Italian parsley leaves
- 1/2 cup extra virgin olive oil
- Slice through the center of each piece of baguette horizontally.
- TO ASSEMBLE THE SANDWICHES: Smear 2–3 tablespoons of butter over the bottom half of each baguette piece.
- If you’re using scallion oil, spoon 1–2 tablespoons of it over and place about 6 slices of rumpled prosciutto on top.
- Put the top half of the baguette over the ham, and squeeze the sandwich together with your fingers to compress it before taking the first bite.
- For the Scallion Oil:
- In a food processor fitted with a metal blade, or with a mortar and pestle, process or pulverize the scallions and parsely until finely chopped. Add the olive oil and process or pulverize another few seconds to combine.
