        $dish=array_push($dish,$item);

Try this

$item[] = array(
                'meal_type' => $meal_type,
                'meal_package' => $meal_package,
                'meal_time' => $meal_time,
                'meal_plan_days' => $meal_plan_days,
                'meal_dish_type' => $meal_dish_type,
                'prefixed_qty' => $prefixed_qty,
                'prefixed_date' => $prefixed_date,
                'cart_plan' => $cart_total,
                'product_rule' => $product_rule
                );

$_SESSION['shopping_cart']['item'] = array_merge($_SESSION['shopping_cart']['item'], $item);
