When your arse is broke, the best thing to do is eat sandwiches.
I kind of was done with it after eating lots of turkey sandwiches in high school, mock grilled cheese in college and grad school, and PB&J always. But I've been getting un poquito creative.
Tuna, you must understand, is a challenge for me. How much mayo is too much? How much is too little? Not until I had no mayo did I realize--none is fine! I've been toasting some whole grain white bread, spreading some white chunk tuna (canned in water) onto the bread, a slice of cheese (muenster or mozz or American--whatev) and nuke for 20 seconds. Then, and here's the kicker, you need something crunchy on top. I'd dig some sprouts, but as have none, used chow mein noodles. Yumsies.
I've also been doing the scrambled egg white on toast with ketchup sandwich thing as well.
Cracked pepper turkey when I have it. All goodness.
And always, PB&J for when I get desperate.
