Dinuguan is a Filipino savory stew of meat and/or offal (typically lungs, kidneys, intestines, ears, heart and snout) simmered in a rich, spicy dark gravy of pig blood, garlic, chili (most often siling mahaba), and vinegar The term dinuguan comes from the Filipino word dugo meaning "blood". Beef dinuguan is same procedure to pork dinuguan.
Here is my own version of dinuguan.
