Does anyone have a really simple diet plan?

I'm looking for a simple plan where I don't have to think much, that doesn't require a bunch of different foods or lengthy food prep. A grab and go kind of thing, or at least quick to prepare. I live alone and am not fond of cooking.

I don't mean diet advice, I mean like, Monday eat this, Tuesday eat this, etc, where I don't have to make decisions. Something balanced and about 1200 calories.
