Combine the farro and water in a medium saucepan. Bring the water to a boil. Reduce the heat and simmer the farro for about 12 minutes until it is cooked through but still has a chewy bite. Drain the farro and remaining water from the saucepan into a fine mesh strainer.
Cut the root end off the brussels sprouts and remove any damaged leaves. Use a food processor fitted with the slicing disc attachment and shred the brussels sprouts. (If you don’t have a food processor, you can use a mandolin to do this. Do not cut off the root end, so you have something to hold on to.)
In a large skillet or sauté pan, warm the olive oil over medium high heat. Add the brussels sprouts and shallots. Sauté them for 4-5 minutes until the sprouts start to become tender and brown in spots.
Then stir in the garlic, salt, pepper, and lemon juice and continue sautéing for 1-2 minutes until more of the sprouts are tender and some are lightly browned and crisp at the leafy edges.
Remove the brussels sprouts from the heat and fold in the farro.
Stir in the lemon zest, parmesan, almonds and parsley.
