> To be clear, you think it's "easy" to live on a diet without any animal products, and also without soy or gluten, and that I'm "weak" for not doing so, despite other health issues I had on the diet?
Yes I do. I'm a vegan and have been for 3 years. In Denmark at least, it's easy to avoid gluten when you buy bread. If it isn't in your country, bake your own. Soy? Also easy. There are thousands of other plants.
> Please tell me what restaurants I could visit with those dietary restrictions?
Any vegan(-friendly) restaurant.
> And what quick lunches / fast food I can buy on that diet, on say a 30 minute lunch break, for instance...?
I eat pizzas, burgers, sandwiches, salats, pasta salats, cold pasta dishes, rice and curry (heated up) and so on for lunch. Anything really. If you can't buy it as take-away, cook your own.
