I don’t think anything’s wrong with that, provided she likes it.  [Not to mention that the gesture itself can be flattering enough to make up for bad food taste.  Pepper’s got a little experience with being the recipient of such an effort, so she at least sounds confident when she reassures him.]  You’re doing this for her, so she’s going to feel pretty special no matter what you make.
 
As for side dishes, a vegetable of some sort would be good.  Maybe a starch just for variety, but only if it’s not too much for you to get done.  When are you meeting her?
