Make the dressing:
In a small bowl, whisk together the shallots, mustard, lemon juice, lemon zest and honey. Stream in the olive oil while whisking continuously until well combined. Season the dressing with salt and pepper to taste. (You can add more lemon juice or agave nectar to adjust the acidity or sweetness to your personal taste.)
Assemble the salad:
In a large bowl, toss together the shredded kale, shredded Brussels sprouts and toasted almonds. Add as much dressing as desired, tossing to combine, then add the cheese and toss. Serve immediately.
To shred the Brussels sprouts, cut off the stems, halve them and using a very sharp knife, cut them into shreds.
To shred the kale, strip the leaves from the stems, stack the leaves on top of one another, roll them up and then cut the roll into ribbons.
