My advice is to learn to cook at least 3 entirely different things. You don't want to make it seem like you have to throw bacon in everything to make it good. Your ideas may be good if you only have to cook one meal, but if she comes over for dinner and stays for breakfast, do you really want to be cooking bacon again? And not only that, but bacon wrapping both things? I understand bacon is great, but you need to change it up.

I would suggest switching up the breakfast. Bacon wrapped eggs is kind of cool, but it's more of a novelty than anything. There's nothing really special or spectacular about it. Learn something like pancakes, and make them better than any you've ever had. That's far more impressive.

Also, you might want to look into wrapping your prawns with pancetta or prosciutto. I think they work better. And make sure you don't just have one dish for each - what if someone doesn't like prawns, cream cheese, or jalapenos? Then what?

For lunch, how about soup and a sandwich? Roasted tomato soup with some variation of grilled cheese (although 'prawns' make me think you aren't from the US...do you call those toasted cheese?). You could add a ton of stuff to grilled cheese to make it more interesting - multiple cheeses, some type of meat, fruit, jams, whatever.
