First, preheat the oven to 425°F so it’s ready. Bring a large pot of water to a boil and generously salt it. Add the baby potatoes and cook until a fork easily slides in — about 10 minutes.
Drain and place the potatoes on a lined baking sheet. Use a fork or flat cup to gently smash them so they flatten slightly. Drizzle with avocado oil and season well with salt and pepper.
Bake the potatoes on the bottom rack for about 20 minutes. Flip them and roast for another 10-15 minutes until the edges turn golden and crisp.
While the potatoes roast, prepare another tray with shredded Brussels sprouts and sliced shallot. Drizzle with oil, salt, and pepper and toss to coat evenly.
Bake on the middle rack for 15 minutes. Then add the kale, toss, and let roast for a final 5 minutes until wilted and fragrant.
In a jar or bowl, combine grated garlic, white wine vinegar, cracked black pepper, chili flakes, white pepper, Dijon, lemon zest and juice, salt, maple syrup, and olive oil.
Whisk or shake until fully combined into a creamy dressing. Taste and adjust acidity, sweetness, or salt as needed.
Once everything’s roasted, transfer the crispy potatoes to the veggie tray. Add edamame and minced chives, then pour about one-third of the dressing over the top.
Toss everything so it’s evenly coated, then divide between bowls. Drizzle extra dressing if you like. Serve immediately warm or chilled later.
