Food.com, My Fridge Food and Kraft are good places to find Ritz cracker chicken recipes. In general, the Ritz crackers are crushed and used as breading for chicken breasts.
In the recipe shown on Food.com, the chicken is dipped in butter first so that the Ritz cracker crumbs adhere. It is then dipped in cracker crumbs and baked. The Kraft recipe is similar, except instead of butter the chicken is first coated in a mixture of mayonnaise and lemon juice. The recipes on Kraft and My Fridge Food both add cheese to the mix, with Kraft using parmesan and My Fridge Food using cheddar.
