Divide the patties into 4 even pieces and roll each piece into a ball.
Brown them in a medium skillet over medium-high heat until cooked through. Set aside.
Back in the skillet, add the oil, garlic, kale and chopped sun-dried tomato.
Sauté the mixture for a couple of minutes, then add the chicken stock.
Now, add the meatballs back to the pan.
In the meantime, boil the orzo in a pot of salted water until al dente.
Transfer the pasta into the skillet, then add lemon and parmesan cheese. Toss it all together and serve immediately.
