How to Make It
In a small bowl, combine bulgur and 1 1/2 cups boiling water. Let stand until bulgur is tender to bite, about 15 minutes.
Meanwhile, stack spinach leaves and cut into 1/4-inch-wide strips.
Place spinach, onions, dill, and cheese in a wide bowl. Pour bulgur into a fine strainer and press out the excess water. Add bulgur to bowl with spinach.
Mix vinegar and oil. Add to salad and mix. Season with salt and pepper to taste.
