Finely chop the onion. Chop the fillets into minced meat (I used a blender). Mix everything;
With wet hands, form 4 sausages and put them on skewers.
Preheat a slow cooker with a grill rack and cook in the closed position for 10 minutes (or on a regular grill).
In one serving there are only about 60 grams, 115.4 calories, 23.7 proteins, 1.9 fats, 0.9 carbohydrates. And the most important thing is that the chicken fillet does not contain excess fat and according to this recipe it turns out juicy and crispy.
Enjoy your meal!
