In a large bowl, toss together the brussels sprouts, pecans, almonds, apples, and craisons. Cover and store in fridge until ready to serve. Once ready to serve, add the strawberries and crumble the feta on top.
Dressing
In a small bowl, whisk together the dijon mustard, honey, vinegar, salt, and pepper. Continue to whisk the mixture as you drizzle in the olive oil to allow the mixture to emulsify. Mix into salad once ready to serve.
