Depending on amount of Chicken you are preparing mix together Sour Cream,  Chopped Onion and Minced Garlic, the chicken will be marinated in this overnight so you want to make sure that the chicken is submerged in the Sour Cream, Onion and Garlic.   Leave in frig for 24 hours marinating then smash the Ritz for the breading of the chicken (I suggest putting the crackers in a large plastic freezer bag and roll over them with a rolling pin until small enough to use for breading).  Take the pieces of chicken out of the sour cream and roll in the crackers.  Place the pieces of chicken on a baking sheet and cook for 30 minutes at 350F.  Make sure to turn the chicken half way through cooking. 

These are great by themselves or served with marinara sauce for dipping and reheat really well, make sure to always reheat in an oven as they get soggy in the microwave.
