Personally, I've found that the tastiest way to go vegetarian is by completely restructuring how I plan my meals.

American food tends to revolve around meat, whereas food in other cultures treats meat as more of a side dish (if it is eaten at all). Indian/Bengali food, Middle Eastern food, (authentic) chinese food...pretty much anything besides American food is very easy to "veganize", since vegetables and legumes are centered more in the meal.
