Heat the oil in a medium skillet. Add the garlic and saute until lightly colored, about 1 minute. Add the meat; cook over medium-high heat, stirring to break up larger pieces, until the liquid evaporates and the meat browns, 3 to 4 minutes. Drain off the fat; transfer the meat mixture to a medium bowl. Cool the meat slightly.

Stir in the remaining ingredients, including pepper to taste.
