in a medium saucepan over medium-high heat. Add onion and cook, stirring, until translucent, 4 to 5 minutes. Add garlic and cook, stirring constantly, for 30 seconds. Add ground chile, cumin and oregano and cook, stirring, until fragrant, about 30 seconds more. Add beans, water and tomato paste; stir to combine. Bring to a simmer, reduce heat to medium-low and cook, stirring occasionally, until the beans are heated through and the sauce is slightly thickened, 8 to 10 minutes. Serve warm.
