Chips "on" Fish with vegetables

Taken from Cuisine at home magazine, this is a more elaborate version of baked fish that I normally make.

Vegetables:
1 large tomato, seeded & chopped
2 leeks, white part only, thinly sliced
1 small green pepper, chopped
1 tbsp garlic, chopped

Fish:
4 red snapper fillets, boned & skinned (flounder or tilapia will work equally well)
1/2 cup coarse bread crumbs
1/2 cup grated Parmesan cheese
1/2 cup crushed potato chips
1/2 tsp paprika
1/2 tsp cayenne pepper
2 tbsp unsalted butter, melted
Lemon wedges & chopped scallion for garnish

Preheat oven to 450 degrees.
Combine the vegetables together, season with salt & pepper & spread on a baking tray coated with cooking spray.
Arrange fillets on top of vegetables, season with salt & pepper.
Combine crumbs, cheese, chips, paprika & pepper, toss with melted butter. Divide the mix over the fillets, pressing gently on the fish.
Bake 20 minutes or so until fillet flakes easily with a fork.
Serve topped with scallion with lemon wedge on side.

Serve with side of asparagus or snap peas.
