A.C.
I keep the ingredients for taco soup at all times. It's brainless, it's super fast and tasty. The whole family likes it (my husband loves it), so when I'm tired or uninspired, that is what I'll do (not more than once a month, but it's there just in case). Cook the meat and an onion, drain, put in a pot with a packet of dry ranch, a packet of taco seasoning, a can of corn, a can of rotels, a can of fire roasted tomatoes, and 1 or 2 cans of ranch style beans (or chili beans). That's it. Once that's all heated up, you can serve with some cheese and tostadas. It's NOT the healthiest or low sodium meals in the world, but we'd rather eat that than fast food anyday, it's tasty.
If we don't do that, I'll either cook up some lo mein, or we can pull a stouffers lasagna out of the freezer and make a salad while it's cooking. OR we could do the grilled cheese sandwich thing: regular for my 2 year old, and "grown up" for the rest of us: the grown up grilled cheese? Instead of american cheese we'll slice feta cheese, a tomato slice and a red onion slice in the middle, and a slice of cheddar. Awesome. Usually, we eat healthy. But sometimes, we just don't want to deal. It happens.
