You'll likely need some help from whoever does the grocery shopping and cooking in your house. Ask them to buy you veggie burgers instead of hamburgers, vegan chicken patties instead of regular chicken patties, and so on.
Are they worried about a veg diet costing too much? Check out these tips for eating on a budget.
They may not want to prepare a whole separate meal for you, so try learning to cook and prepare some meals for yourself. Consider at least learning how to fry or microwave your vegan meat, tofu, or other main dish. It's easy to do, and it's a skill you'll need in college.
Meanwhile, chow down on the side dishes the whole family is having—things like pasta, potatoes, vegetables, rice and beans, and so on. You can also keep satisfying snacks around the house for when you need something quick, like microwave burritos, granola bars, canned lentil soup, and nuts.
