I've also heard great things about the Lightlife products although they're not yet available here (Canada). I've heard they're coming soon though. If you're looking for other great products there's a company called Yves, it's a Canadian company but I think the products are available in some places in the US. I think their website is www.yvesveggie.com
They have hot dogs and deli slices but my favourite product is their Just Like Ground. It's great to substitute for ground beef. I've used it in sauces, lasagna, tacos etc. I love it!!
