In a large bowl, mix the chicken, rice, carrot, zucchini, chopped parsley and Chia seeds well, and then form four patties. Heat a large frying pan on medium to medium-high heat, add oil and cook patties for about 5 minutes on each side. Reduce heat if browning too quickly. You can also cook on a grill. To serve, cut foccacia bread buns in half and spread a little mayo and ketchup (or tomato chutney) on bread. Place a piece of cheese, if using, on the bottom pieces then add a burger patty, tomatoes, greens and red onions if desired. Place top on and gently press down. Serve burger patties on a bed of mixed greens for a lighter meal.

Tip: You can substitute chicken with ground (minced) beef, turkey, fish or prawns if desired.
