Heat the oil in a large skillet over medium-high heat. Add the ground beef, and season with salt and pepper. Cook, breaking up the meat with a wooden spoon, until browned and cooked through, about 4 to 5 minutes. Spoon off any fat. Add the chili powder, cumin and coriander. Cook, stirring, until fragrant, about 1 minute. Stir in the water, and cook, stirring often, about 30 seconds. Season with additional salt and pepper to taste.
