Prepare the ingredients as instructed above.
Heat olive oil in a medium pot over medium heat. Add chorizo slices and cook 2–3 minutes per side until lightly crisped and the oil is tinted red.
In the same pot, add the chopped onions and sauté for 3–4 minutes until softened and translucent.
Add the diced potatoes, chicken stock, salt, and pepper. Bring to a boil, then reduce to a simmer. Cover and cook for 15 minutes, or until the potatoes are fork-tender.
Stir in the kale and cooked chorizo. Simmer uncovered for 5–7 minutes until the kale is tender but still vibrant. Taste and adjust seasoning as needed.
While the soup simmers, warm the crusty bread.
Mix together the milk, cinnamon and honey until combined.
Serve the caldo verde with crusty bread, and cinnamon-honey milk.
