>There were no expensive ready meal options at my local supermarket - Labeling contains no information about what kind of environment animals are brought up in

I think you know why. :)

>Ultimately I wish I had the will power to turn fully vegetarian

The way I started (I'm a veggie now) is not to fully eliminate meat completely for your diet, but just 1 day a week.

The way to look at it is not that you're missing out on meat for 1 day, but as an opportunity to try out non-meat options.

Here's some suggestions: go to a middle eastern place and order falafel wraps, or tofu next time you go to a Chinese place. Also there's lots of Indian food that's veggie friendly. i.e. Indulge your palette in food that you generally wouldn't try. You might like it!
