There's a range of ingredients, you've probably noticed in the supermarket, called Mexican Discovery. I prefer them to Old el Paso (which I can also get here).
The nice thing about Mexican Discovery is that they sell half cans of refried beans (and they're a little spicy, too). A whole can is always a chore to get through (and DH wouldn't touch Mexican).
I seldom made Mexican food in the States because it was so plentiful (with variable quality, of course), but I've added burritos into my lunch repertoire. Soft flour tortillas freeze well and thaw in seconds. And, this time of year, homemade salsa with stuff from the garden is the best.
