Have you tried some good alternatives to meat? Like, try seitan* crumbles in a taco. With all the spices and other toppings it's really hard to tell the difference. Also, I find it almost impossible to tell an Impossible Whopper with Cheese from a regular Whopper with Cheese, after all the glop they put on it. I know those are both bottom-of-the-barrel meat choices, but maybe branch out and try a thing or two. If you don't like it - no biggie.

I've tried casually dipping my toes into the vegetarian pool with just occasional meat substitutions. Occasionally I find something that's "No way" but more often than not, I find something that is also really tasty. It's not meat, but it's also tasty in a different way, so I don't miss meat as much. I've found vegetarian dishes I actually like. My biggest problem however is getting enough protein in my diet when I start eating mostly veggies.

[* Seitan only if you can handle gluten. Because, it's like 100% gluten! ]
