Combine Ritz cracker crumbs with melted butter.

Press into the bottom of a 9" or 10" springform pan to form the crust.

Bake the crust in a preheated oven at 300°F for 10 minutes.

Beat cream cheese until fluffy.

Add eggs, one at a time, to the cream cheese.

Stir in flour, salt, and white pepper.

Fold in finely chopped onion, shredded carrot, and finely chopped bell pepper.

Pour the mixture into the prepared springform pan.

Bake at 300°F for 1 hour.

Turn off the oven and let the cake cool in the oven for an additional hour.

Refrigerate the cheesecake before serving.
