Chicken Burgers

I just need some quick advice for dinner tonight.  I am running home right after work and then running out just as quickly to attend a cocktail party (where I will drink club soda, thank you!).  Anyhow, I picked up these pre-made chicken burger patties from Trader Joes yesterday.  They seem pretty basic- just a little seasoning in them, no major add-ins.  I also have whole wheat buns.  My question is, what else should I put on it to make it taste good? I've been looking online to find some good recipes but all the sauces, etc that I find seem to have a gazillion ingredients.  I just want something that I can quickly top it with to give some flavor and yumminess.  As a side I will make asparagus with olive oil and lemon.

- Grilled or Sauteed in Olive Oil Onions 

- Sun Dried Tomatoes

- Olive Tapenade

- Tomato Paste

- Sauteed Spinach &/or Bell Peppers 

- Good Ol' Mustard! 

- Salsa 

thank you!  I actually did the spinach and onions sauteed- yum!!
