Help spicing up a recipe

[ketherian]

Hi - long time lurker, first time poster.
Last night I made up Southwestern Steak, Corn, and Black Bean Wraps (from the July 2005 issue of Cooking Light magazine, p210 by Barbara Seelig Brown Magazine or registration required).

The fajitas/wraps are filled with:

• lime juice
• cumin
• red onion
• black pepper
• corn
• black beans
• cheese
• beef (flank steak grilled with minimal seasoning)

The recipe was very good, but ... lacking something. Anyone have any idea how to spice things up a little? I'd rather spicy than hot. My initial idea was to add salsa - but that would make the mix very wet.
