My husband goes to BA often and he would like to have chimichurri at home. How can I prepare it? If your husband often travels to Buenos Aires I recommend he buys chimichurri jars (vacuumed sealed) in the supermarket. It wont be as fresh as the one you can prepare at home but you may not find the correct ingredients. Anyway, here is my recipe: - I cup finely chopped parsley - 10 garlics (pieces) - 1 cup finely chopped onion - 2 red peppers super finely chopped - 3 tomatoes super finely chopped - 6 tablespoons of red vinager - 1 to 1/2 cup olive oil - a pinc of salt and a squeeze of lemon juice.
