In a bowl, combine cream cheese and Ricotta cheese, stirring until evenly incorporated.
Add the oil from the jarred peppers as needed, 1 tablespoon at a time, to thin out filling if necessary. (The filling should be the consistency of whipped cream cheese).
Season to taste with salt and pepper.
Fill each Piquante with about 1/2 teaspoon of filling (depending on the size of the pepper).
If needed, with clean hands, press the filling into the pepper with your fingers.
Serve immediately or refrigerate for up to 2 hours; let come to room temperature for 15 minutes prior to serving.
