Looking for a dinner that's flavorful, healthy, and can be prepared in minutes? Fish and vegetables are a good bet. Tilapia is a budget-friendly white fish that cooks quickly, making it a snap for weeknight meal plans. However, substitute other types of white flaky fish, such as cod or halibut, in place of tilapia if that's what's on special at the grocery store this week. Serve the baked fish and veggies alongside rice pilaf, lemony orzo, or buttered potatoes.
