Hey Capt, if you're going with a Cuban theme, you could possibly have some sort of a steak salad using strips of grilled flank steak, diced onions, fresh cilantro, and freshly squeezed lime. For a simple side dish, you could go with Cuban rice (fried rice with peas, diced onions, carrrots, slivers of scrambled egg, and smoked ham cut into cubes). And for dessert, you could go with plantains glazed with caramel (just melt sugar till its caramelized, add vinegar till dissolved, and then some water, lime zest, and cinnamon) with some vanilla or cinnamon ice cream on the side.
Oh yeah, and your Siglo to top it all off!! 8)
