Heat oven to 375°F. Heat 2 tbsp. oil in medium heavy-bottomed saucepan oven over medium-high heat. Add chorizo and onions; cook until onions soften and chorizo starts to brown, about 10 minutes. Add garlic and sazonador; cook until fragrant, about 30 seconds more.
Stir in ham concentrate mixture, beans and tomato sauce; bring to boil. Reduce heat to medium low. Simmer, stirring occasionally, until slightly thickened, but still soupy, about 10 minutes. Pour bean mixture into large baking dish.
Meanwhile, heat remaining 2 tbsp. olive oil in small skillet. Add breadcrumbs. Cook, stirring frequently, until light golden brown, about 5 minutes. Sprinkle crumbs evenly over bean mixture.
Cook casserole until liquid begins to bubble around edges and breadcrumbs are browned, about 25 minutes.
