Becoming the only vegetarian in a household?

Alright, I’ll start with a little background. I eat a predominantly vegetarian diet already. Not on any particular principals… I just don’t really like to eat meat. I do like fish and chicken, but I don’t think I would miss eating chicken at all. I eat a wide variety of vegetables every day, and always have as far back as I can remember. I am also a fan of vegetarian substitutes, like Boca. My husband and his children, however, are meat & potato types. They want nothing to do with veggies. (except corn, of course.. that’s always the exception.) The boys don’t live with us full time, which usually leaves me and my very picky husband.

I suppose I’m wondering if it’s next to impossible for me to eat a 100% vegetarian diet and still prepare food that my husband will eat… without being wasteful or spending more money on groceries. Has anyone been in this position before? Being the primary cook in the house and wanting to eat a drastically different diet than the rest of the household? How did you manage it? Is there an easy way to prepare a meat based meal for one person/one sitting? (he doesn’t like leftovers, either… lol.)

I just feel a bit stuck, so any tips or suggestions are welcome (shy of suggesting that I tell my husband & the boys to fend for themselves in the kitchen.)
