Preheat oven to 425°F and line a large baking sheet with parchment paper, or spray with nonstick spray.
Add the potatoes and brussels sprouts directly onto the baking sheet. Drizzle with olive oil and sprinkle with salt and toss to combine using a spoon or your hands. Place the baking sheet in the oven and roast for 25-30 minutes, flipping halfway through.
While the veggies are roasting, make the dressing: whisk the olive oil, garlic, lemon juice, honey, dijon, apple cider vinegar, salt, and pepper together in a bowl or glass measuring cup; set aside.
Next, cook the bacon in a skillet over medium heat, then transfer to a paper towel.
Add the kale to a large serving bowl or platter, then drizzle HALF of the dressing over top and massage the kale with your hands, which helps to make the kale less bitter and more flavorful.
Once the veggies are done, add them on top of the kale, along with the bacon and goat cheese.
Add more dressing to taste and enjoy!
