Scrub potatoes, then poke each several times with a fork (making sure to press well into the potato flesh).
3
Place the potatoes on a baking tray, and bake for 50-60 minutes, until tender. Once cooked, remove from the oven.
4
While the potatoes are cooking, prep the kale leaves: Wash and dry, remove and discard the thick inner stems, and roughly chop the leaves.
5
Cook in a pot of rapidly boiling water for 2 minutes, then drain and run under cold water to stop cooking process. Set cooked kale aside.
6
Slice potatoes lengthwise, and scoop the insides out into a blender, leaving a good 1/4 inch of potato flesh still attached to the potato skin (otherwise, your potato might fall apart). (Note: If you don''t have a blender, you can use a hand blender, a food processor, or simply mash the ingredients with a fork!)
7
Add the broccoli, kale, and milk to the blender and blend until smooth. Season to taste with salt and pepper.
8
Scoop the pureed broccoli-kale-potato mixture back into the potato skins. Sprinkle with the grated cheddar cheese, return to the baking sheet, and bake for another 10 minutes.
9
Change the oven setting to broil, and continue cooking on high for 3 minutes to brown the cheese. Remove from the oven and serve!
