To cook farro. Bring 3 cups of water to a boil in a kettle. Heat a heavy saucepan over medium heat, add the farro and toast it slightly, stirring until there is a toasty aroma. Turn off the heat, stand back and gradually add the water (it will bubble and foam up). Add ¼ teaspoon salt. Return it to a boil, then reduce the heat, cover and simmer until tender 20-30 minutes. Turn off the heat and let it rest for 10 minutes. Drain off any excess water and fluff with a fork.
Meanwhile, preheat oven to 400. Place asparagus and prosciutto on baking sheet, drizzle with olive oil and salt and pepper. Toss to combine. Roast for 7-10 minutes.
To make poached eggs. Heat 1 ½ inches of water in a small non-stick skillet to boiling. Lower heat until the water barely bubbles. Break the eggs one at a time into a shallow bowl and ease them into the water one at a time. Spoon water over the top, cook 3 - 5 minutes. Remove with slotted spoon, draining off water. You can place on a paper towel to pat dry if you'd like, I usually don't bother.
Divide farro among four serving bowls. Tops with asparagus and prosciutto. Squeeze a wedge of lemon juice over the top. Place poached egg on top and sprinkle with salt and a generous grind of fresh black pepper.
Notes
Use any of your favorite grains in place of the farro - spelt, brown rice, bulgur even quinoa. Can substitute bacon or pancetta for the prosciutto.
