Prep Work: Mix panko through garlic cloves in a ziplock bag. Chop zucchini. Cut potatoes if serving. Make home made tartar sauce if desired with recipe at end.
Preheat broiler. Grease broiler pan and a baking sheet with olive oil.
Beat egg in a shallow dish with a fork until blended. Combine panko and next 3 ingredients in a seperate dish.
Salt and pepper fillets. Dredge fillets through egg and then panko mixtures. Place on greased broiler pan.

Place both trays under broiler for 4 minutes. Then turn over fish and stir zucchini; broil 4 minutes more. Remove fish when it flakes easily with a fork.
Put zucchini on top rack with low broil and check every few minutes, flipping when browned. Serve all with dipping sauce and lemon wedges.
