There is absolutely jack-diddly here. Tulsa and OKC probably have some better stuff, but Costco doesn't seem that prominent in Oklahoma.
I loved some of the stores in Florida from my vacations there... I was like, "why can't WE have Publix or Dixie or whatever?" I can't remember all of the names of places.
My KitchenAid was a wedding present too. Red. I lurve it!! I like my mashed taters a wee bit lumpy though, so I do those by hand. Just a preference.
For the frozen food, maybe you could prepare it as much as possible without actually cooking it? Like, mix the spices and put them in a baggie, make the sauce and put it in a baggie, and have the meat all ready... then freeze it like that, so that all you have to do is cook it, rather than reheat it? That woudln't work for time saving for some things, I know. I have problems with cooked food tasting a bit off too. You know what's great?? Lasagna!! You get it all put together and then freeze it instead of cooking it - stays great for months. Just pop it in the oven! You can even cook it from being frozen, just add a little bit of cooktime.
