In a large bowl stir together egg, parsley, yogurt, Dijon, Worcestershire, Old bay, hot sauce and lemon zest.
Add tuna and saltine cracker crumbs. Fold gently to combine.
Line a baking sheet with parchment paper. Using a 1/3 cup measuring cup, scoop out some tuna mixture. Press the mixture into the measuring cup lightly to form a patty. Invert the patty onto the baking sheet. Repeat to make 6 patties.
Bake at 450 °F (232 °C) for 12-14 minutes until golden brown. Serve with lemon wedges.
