1 teaspoon drained capers (or 1–2 anchovy fillet if you aren’t vegetarian)
1/4 –1/2 cup water
3/4 teaspoon salt
Fresh black pepper
Salad:
1 head Romaine lettuce
2 cups croutons
1/4 cup grated Parmesan, if you like (not vegan, obviously)
Instructions
Make the dressing (allow several hours or make the day before): Soak cashews in about a cup of water for at least 4 hours and up to 12. Drain.
Combine dressing ingredients in a blender jar or food processor. Drain the cashews before adding and discard the soaking liquid. Add 1/4 cup water and blend. Add more water if necessary to get a pourable consistency.
Wash and tear Romaine. Refrigerate until cold and crisp.
Toss with about 1/4 cup of dressing and garnish with croutons or Parmesan.
