Preheat oven to 350 degrees. In a bowl, combine crackers with melted butter and press into the bottom of a springform pan. Combine cream cheese, sour cream and eggs in a bowl until smooth. Stir in cheese, garlic, onions, pepper and Worcestershire. Pour over crust and bake for 30 minutes or until the cheesecake is set and firm in the middle. Allow it to cool on a wire rack. Refrigerate until serving time.
When ready to serve, remove the cake from the springform pan and transfer to a serving platter. Make an outer ring of green pepper jelly and fill the center with red pepper jelly (use amount to taste). Top the green jelly outer ring with toasted pecans. Cut into wedges and serve with Ritz crackers.
