My girlfriend wants me to make breakfast for her on monday. I need help!

All of you people are missing the big issue here. Telling him to go above and beyond his cooking skills just aren't going to hack it here.

Take my advice, because this is from tried and tested experience:

KISS (Keep It Simple STUPID)
Eggs and bacon, with toast, while not complicated, can be more than adequate when given the proper presentation.

The key here is to make her feel special. Certainly this can be done with an extravagant meal, but it can also be done with a simple dish, presented to her in an extravagant manner. Get a tray with the little 6 inch feet things on the side and serve her breakfast in bed. If she goes for the "princess treatment" thing, even offer to feed her each bite. Make a big production out of how you are her undying and eternal servant, and would go to the ends of the earth for her, etc, and kiss her between bites that you feed her. [note: Do NOT make baby noises as she's eating, or move your mouth as if you're chewing the bites]
Yes, she will probably find this highly corny, but provided she isn't the type to think you're up to something or that you're making fun of her, she WILL enjoy the treatment. Just make sure that you're sincere about what you're saying. Use your own judgment when deciding how far to take the whole routine, don't go past the point where you can be sincere about it, but don't let mild embarrassment hold you back.
If she makes an issue about how simple breakfast is, then just be honest and admit that breakfasts aren't something you have much experience with, but you did the best you could. If you think you're up to it, ask her to teach you how to prepare the more complicated breakfasts that she does. Alternately, you can also use the tactic of point out that this is merely the appetizer, and knowing your own skill level, opted to take her out to breakfast where she can get a proper meal.

Wake up a little early, preferably before she does, or when she starts to stir, tell her to sleep in and relax while you take care of things. Do scrambled eggs or maybe an omelet. The key with these is to use extremely low heat, be patient, and make sure you sprayed the pans with pam or oil to be sure you don't have everything sticking. Provided the heat is kept low, the scrambled eggs can usually be cooked completely through before it will start to singe on the bottom. don't try to flip them while they're still soupy on top, it won't work.
If you think you can handle something of a higher skill or preparation level like pancakes or waffles or an omelet, go for it, but keep in mind; be extra cautious about any mess that you make, because the effect will only be complete if you are able to clean everything back up on your own, preferably before she even sees it.

So there you have it. Ultimately, the tastiness of the food is important, but still secondary to the effort you make to dote on her. So if there's one thing I would say is the most important, it's to make sure that you don't act like this is a chore or a trial for you to get through, but something you are more than willing to go through for her sake.
