1tablespoonof minced parsley or cilantro(both work)
1/2cupof sour cream
For the chicken
To cook the chicken: Heat oil over medium-low heat. Stir in the onion and cook until they start to become translucent. Stir in garlic and pepper flakes, cook stirring for half a minute. Add bell pepper, tomato and chicken. Stir to mix. Pour in tomato sauce and stir to mix. Cover and simmer until the liquid has evaporated. Set aside.
Cutting cheese: Using a cookie cutter, cut the cheese into 12 small circles (about the size of the crackers), if you don't have a cookie cutter just cut the cheese into squares.
Serving: Arrange chicken, cheese, crackers, parsley and sour cream on a tray. Right before eating assemble by placing cheese on a cracker, topping with chicken, followed by a small dollop of sour cream and sprinkle with parsley. The cheese will prevent the cracker from becoming soggy with the chicken juices, but is best not to pre-assemble.
