Red, yellow and green poivrons are available year round and are essential ingredients in a piperade or a ratatouille.
The mild red triangle-shaped ones sold in jars, essential in many Basque dishes, are piquillos.
Some specialty grocers also sell padróns, thumb-sized green peppers from Galicia, Spain, which are good fried in olive oil and salted as an aperitif snack (or breakfast, in Galicia!). Some are hot (piquante), most are not.
