Yes -- more recipe advice, please, less snarking!
Road trips can be difficult for vegans, yet another reason to learn to cook well. The Moosewood Cookbook (the original one) has a great recipe for samosa, those spicy potatoes-and-peas Indian treats; you can make these vegan very easily, and they'd be awesome on a car trip, little packets of spicy goodness.
Sandwiches aren't so exciting for most vegans: unless you find a recipe for a tofu salad that you like, you'll probably be stuck with PB&J, which gets old fast.
For a change, try slicing tempeh into thin strips, soaking it in soy sauce and garlic and a little brown sugar for a few minutes, and then frying it up in oil. It becomes a vague approximation of bacon, inasmuch as it's fatty, salty, slightly sweet protein, and is good for breakfast or (presumably) for "B"LT sandwiches. (I use it in quiche also, but that's not vegan).
STAY AWAY from fake cheeses. Unless you're partial to eating latex, you'll not enjoy the experience. Soy milk, soy ice cream, and the like can be good. Fake cheese is just nasty.
Of all the fake meats, the new bratwursts are my favorite. They're spicy and good (you may be noticing a theme: I think spicy is a great trait for vegan food to have). Baked tofu is also a fun thing to take on picnics and hikes.
What sorts of food do you like eating if avoiding meat weren't a goal? I might be able to direct you toward some vegan foods that would satisfy the same cravings.
Vegan foods are often pretty gross when they try to imitate meaty/dairy-y foods. But sometimes you can recognize the core traits of a desired food (it's salty and greasy and deep-flavored! It's chewy and moist and spicy! It's sweet and soft!) and can come up with some food that has similar traits that's vegan.
