Tortellini alfredo, roasted vegetable lasagna or a pesto pasta dish could be an affordable entree, additionally they are vegetarian. Otherwise, I think there are all kinds of ethnic/regional cuisines that could fit the bill. Cajun: Jambalaya or Gumbo w/ rice Mexican: Pork Carnitas, Beans & Rice, or you could do a Cuban spin with citrus marinated cuban pork roasts and make black beans and a coconut rice, Asian: Terriyaki Chicken, Steamed Rice, and Asian Cucumber Salad, Southern: The Pulled Pork was a great idea, or it could be something like Chicken & Dumplings. The big question is WHO IS YOUR AUDIENCE, or in this case diner.
