Spear the chicken, pepper, zucchini, and mango on a wooden skewer, continuing with the pattern until the skewer is full. Repeat with other skewers until all the ingredients are used.
In a bowl, stir together the olive oil, lemon juice, and oregano.
Brush the mixture over the skewers.
Spray a skillet with nonstick cooking spray.
Over medium-high heat, cook the skewers, turning occasionally, until the chicken is cooked completely and the other ingredients are browned.
