I find that same inconvenience with vegetarianism. Family gatherings are difficult when it comes to mealtimes, not only for the non-meat issue but also because we mainly eat organic. Unfortunately I haven't found a good solution to this one yet ... taking food along is an option but not always a convenient or practical one.

My biggest concern with veganism would be the health aspects, but if you're used to a vegetarian diet you may already be getting the protein and other nutrients you need from vegetable sources. I rely on eggs and cheese for protein and sometimes even have to eat fish or chicken, or else I just can't get enough protein and my health starts falling apart. If you can do it and remain healthy, then I say go for it ... ideologically I'd prefer to be a vegan but practically am not sure I'll ever be able to do it successfully.

Tofu doesn't have much of a flavor in and of itself, which makes it great to use in a wide variety of dishes because it absorbs the flavors of whatever else is in the dish. Even the extra firm tofu can be soft/squishy, but if it's frozen for a day or two and thawed before use, it has a firmer more "meaty" texture.

And I wholeheartedly agree with Julia, even little things to show support go a long way.
