Cook the brown rice according to the package instructions and keep warm.
Bring a large, covered pot of water to a boil. Add the potatoes and simmer until they just become tender, 6 to 8 minutes. Add the beans and peppers and continue to cook until potatoes are tender and beans are crisp-tender, 3 to 4 minutes more. Drain and rinse in cold water, then shake dry.
Whisk together 2 tablespoons each of the oil and herbs, the lemon juice, mustard, olives, 1/4 teaspoon salt and some pepper. Add the cooked vegetables and toss together. Set aside.
Preheat the broiler, position an oven rack 4- to 6-inches from the broiler and line a baking sheet with foil. Mix together the breadcrumbs, the remaining 1 tablespoon olive oil, the remaining 1 tablespoon of herbs and the paprika. Arrange the fish fillets on the prepared baking sheet and sprinkle all over with 1/2 teaspoon of salt and some black pepper. Broil the fish until it starts to turn opaque, 3 to 4 minutes. Remove, sprinkle with the breadcrumb mixture and continue to broil until flaky and cooked through, 3 to 4 minutes. (Be sure to keep an eye on the fish as the breadcrumbs can burn quickly.)
Divide the fish, bean-potato salad and rice among four dinner plates. Serve with lemon wedges, berries and milk.
