Mix together the tuna, mustard, bread, lemon zest and juice, water, parsley, chives, and hot sauce. Season with salt and pepper. Mix in the egg.
Divide the mixture into 4 flat patties.
Heat the olive oil in a pan over medium-high heat. Place the patties in the pan and cook until browned - about 5 minutes each side. Higher the heat, the more texture on the outside - but flip them sooner.
Serve with lemon or lime wedges. Prepare a fresh green salad to go with this for a full, light, meal.
