Steam the kale
Set up a steamer basket over high heat. Remove the tough ribs from the kale and chop roughly. Lightly steam the kale until bright green and tender, 1-3 minutes. Remove from the steamer and dress it with a bit of olive oil, salt and pepper.
Cook the JUST Egg
If using JUST Egg Folded, heat up in a toaster, oven, skillet or microwave according to the directions on the box.
If using JUST Egg, scramble (like an egg) in non-stick skillet over medium heat with a bit of oil. Stir occasionally, letting it set into large curds that will hold together nicely in a breakfast sandwich. Once the liquid is cooked through, remove from the heat.
Assemble the sandwich
Lightly toast the whole wheat buns. Layer each bottom bun with sliced avocado, sprinkling the avocado with flaky salt and black pepper. Top the avocado with the JUST Egg, followed by the steamed kale and kraut. Close the sandwich and enjoy immediately.
