Preheat oven to 350°F. Place sausages, potatoes, brussels sprouts on a sheet pan and drizzle on 3 tablespoons olive oil, toss to coat. Sprinkle lightly with salt and pepper.
Place in oven and bake for 30-35 minutes or until vegetables are tender and sausages are cooked to 165°F, turning over halfway through cooking.
Meanwhile, whisk together remaining ingredients, except almonds, until emulsified.
Remove sausages and vegetables from the oven and transfer to a serving dish if desired.
Drizzle on sauce and sprinkle with almonds. Enjoy!
Notes
*Potatoes should not be more than twice the size of the brussels sprouts for even cooking.
