Cut the lamb into uniform pieces and cut the onion into pieces smaller than the lamb and place on the stick in an onion, lamb, and onion pattern.

Sprinkle with salt and pepper.

Mix the other ingredients and marinate the skewers overnight.

Cut the chicken into uniform pieces. If the chicken is one inch thick, the onions should be cut a bit smaller.

If the onion is thicker than the chicken, then the meat won't get into contact with the heat source. Direct contact is necessary for the meat to caramelize and get that nice brown color and hearty flavor.

When putting the ingredients on the stick, start with an onion slice, and continue with a sage leaf, chicken, sage, onion pattern.

Sprinkle with salt and pepper.
