Preheat the oven to 425 F. Line a sheet pan with parchment paper.
Prepare the veggies as indicated (peeling, dicing, etc) and then put everything up to the mushrooms on the sheet pan.
Drizzle the veggies with the olive oil and then sprinkle with the thyme and sea salt. Toss to coat. Roast for 30 minutes, adding the chopped kale to the sheet pan in the last 10 minutes.
Meanwhile, put the ingredients for the stewed berries in a small saucepan and bring to a boil, then simmer uncovered for 20 minutes.
Serve warm. Especially good when served drizzled with the stewed berries for a sweet and tangy flavor punch.
