You can make vegan sushi, tastes good (its a common myth that sushi is all about raw fish and rice, there's tons of traditional vegetarian stuff)- you can put all sorts of fillings in it like avocado, boiled carrot, cooked mushroom, peppers, de-seeded cucumber etc
.
The vegan diet tends to be quite lacking in the essential B12 (which is largely obtained from animal products), without you will suffer nerve damage and other issues like blindness etc, so its vital that you find a way to supplement it in your diet if you decide to become vegan. Info;

Don't forget that there are loads of vegetarian meat substitutes, so you won't necessarily need to stop eating recipes which are based on animal products. Most vegetarian meats taste rather bland and vaguely gamey in flavor and tend to go very dry very easily (because they have no animal fats in them to keep them moist), however you can really knock them up a notch by adding stuff like tomato pasta sauce, soy sauce, worstershire sauce, olive oil etc and stuff like chopped tomato's and spring onions, sweetcorn, cooked pea's, grated carrot etc and seasoning like paprika, salt & pepper, oregano, parsley, sage, vegetable stock and gravy etc
. You can do a really decent mince for pasta or cottage pie or filling for burito's with seasoned and sauced up vegetarian meats like these

I'm not a vegetarian myself however i eat little meat (only eat animal products obtained from good sources), partly to help maintain a good body weight and partly because if all i have available to me is stuff like battery farmed food, i'd rather not eat it than eat it. But my fiance is vegetarian (purely because he doesn't like the taste of meat- his parents were both vegetarians and so they never fed him meat and thus he's grown up not really liking the taste of it etc) so i end up doing a large amount of vegetarian cooking for him on a regular basis. Don't forget stuff like pasta, vegetable stir frys, soups, roasted vegetables like potato wedges (sweet potato wedges taste awesome BTW) and peppers etc

edit: If you do decide to do potato wedges, don't peel the potatoes just wash them thoroughly to remove any dirt on them. Then dry them very thoroughly and quarter each potato (each slice should be about an inch thick) and then dry each slice off with a towel (potatoes are very starchy and if you don't wipe the starch off the wedges will be kinda soggy when cooked instead of having a nice crispy skin).
Place all your wedges in a large bowl and then put a generous helping of olive oil on them, and sprinkle paprika generously on all of them, add a little cumin, and salt and pepper to taste, and then mix all the wedges in the seasoned oil thoroughly (if you have a lot of seasoned oil left over afterwards, its great when drizzled over a salad). Then place them in an oven (which has been pre-heated to 180 degree's C) on a baking tray- make sure the wedges aren't piled on top of each other though, you don't want them touching (otherwise the ones which touch won't be very crispy). If you are just using ordinary potatoes they'll take about 30mins in the oven until they're cooked, if you are using sweet potatoes though they'll only take about 20mins
. Then once they're done, tuck in- great on their own or with ketchup or a dipping sauce like a mild thai chilly sauce, or chucked into a hearty salad etc
