Start by crisping the ground beef in a pan until it's nicely browned.
Add the thinly sliced lacinato kale to the pan and toss it with the beef.
Incorporate the toasted pine nuts and the finely diced roasted red peppers into the mixture.
Squeeze in the juice of one lemon to brighten the flavors.
The warmth from the beef will slightly wilt the kale, keeping some of its crunch and adding a fresh taste.
For the sweet potato purée, slice the sweet potatoes very thinly so they cook quickly.
Boil the sliced sweet potatoes in the chicken bone broth, stock, or water until tender.
Serve the beef and kale mixture over the sweet potato purée, seasoning with kosher salt and black pepper to taste.
