Cut sweet potato into bite sized pieces, about ½ to 1-inch in size. You want your sweet potato chunks to be roughly uniform in size so they all cook at about the same rate.
Place the cubed sweet potatoes in a large cast iron skillet or on a baking sheet, and drizzle with 1 tablespoon of the oil, sprinkle with Adobo seasoning, and toss to coat. Roast in 400° F oven, turning occasionally, for 25-30 minutes, or until crisp and browned outside and just tender inside.
While sweet potato roasts, heat remaining 1 tablespoon oil in a medium sauce pan over medium-high heat. Add onion, and cook 10-20 minutes or until starting to turn golden brown, stirring occasionally. Add in minced garlic and Recaito, and cook for an additional minute. Stir in cannellini beans and heat through.
