Place vegetables in a large bowl. Drizzle with cooking oil, sprinkle with salt and pepper.
Prepare the skewers:
Thread chicken and sausage on skewers together. Set aside.
Thread vegetables on skewers separate from chicken and sausage.
Heat grill to medium high. When heated, place skewers directly on the grates.
Cook chicken and sausage for 5 minutes. Flip and continue cooking 5 minutes longer or until internal temperature of the chicken reaches 165 degrees.
Cook vegetables for about 2 minutes on one side until slightly charred. Flip and do the same with the other side.
Serve over a bed of cooked Basmati rice.
