Mashed potato tacos

I'm not quite sure what this says about me, but I found a link to this recipe on one of the message boards I frequent and I cannot stop thinking about making it. Not only have I decided that it is perfectly acceptable for T and the kids to eat omelets for dinner while I eat a vat of guacamole with chips (I added some lettuce and some tomatoes so I feel like it was actually a fairly healthy meal for me), but now I am dreaming of eating mashed potato tacos. No, I am not pregnant. Mashed potatoes, cheese, sour cream, french fried onions, taco shells, what more could you ask for? Of course I was thinking that perhaps it might taste even better with cream cheese instead of sour cream. I might end up declaring myself too lazy and just eating the entire can of french fried onions though, so I should resist the urge to buy the ingredients.
