Remove any ragged or old-looking outer leaves on the brussels sprouts and discard. Parboil the brussels sprouts (or steam them) for 3 minutes or until just tender. They should be almost cooked all the way through (split one in half to test). Strain the hot water and place the sprouts in a bowl of ice water, this will keep their color bright green. Cut the sprouts into halves.
Remove the pan from the heat, stir in the lemon juice and half of the toasted almonds. Add salt and pepper to taste. Place in serving dish and garnish with the rest of the toasted almonds.
