Cesar Salad EVERY time.
That is mainly because i have a fear of "do it yourself food".
For example, when we have taco's, or even taco salad for dinner, i end up with these wimpy ass tacos that have all the same ingredients as my wife's but her's look like they should be put in some food magazine, mine look like a child threw shit on a plate. Same thing at salad bars. Everyone has this amazing looking salad thats like 40' high and just beautiful. I come back to the table with this wimpy looking thing that doesn't even look edible. So, when i was about 13 years old i decided that I should never EVER go to a salad bar and just have my waiter (or however that restaurant does it) make me a salad because it ALWAYS looks better and tastes better than anything i would have made my self.
My answer is obviously salad...as long as i dont have to put it together....otherwise, I'll go for soup cause you cant fuck up soup.
