It's Taco Thursday y'all

So one thing I haven't quite gotten down is the whole dinner thing. I know, I know- K is almost 9 months old- how do I not have dinner down?

I have a bit of an unusual schedule. 3 out of 5 days a week I'm working late or something comes up and I don't get home before 7. My husband, though nice to look at, isn't much help in the kitchen. Like, at all. He makes a mean pancake but you can only eat those so much so our dinners tend to be frozen chicken nuggets and if I have some extra energy- some mac-n-cheese. Tonight it was Taco Thursday, last night it was spaghetti with meat sauce. That's only 2 days and I'm already exhausted from browning the meat, making the rest of the meal, washing the dishes...

I need help. I need some quick meals with few ingredients as possible. I got a crockpot for Christmas and I'm excited to use it but I still have those silly thoughts of burning my house down while at work.

I'm just a mess. How do you do it? Do you do a weekly meal planner, a monthly one? Do you do the same few meals over and over? Do you just not care and eat cereal at least twice a week? Shoot me some advice folks- I need all the help I can get! Thanks!!
