Heat up a skillet on high heat, add the olive oil. Saute the garlic until aromatic but not browned, add tomatoes and shrimp. Stir to combine well. As soon as the color of the shrimp turns opaque, add the beer.
Bring the beer to a quick boil and when the shrimp is cooked through, turn off the heat and add the parsley. Stir to combine well and serve immediately.
