I am a Yonkers resident, and don't often get up to Briarcliff Manor. On those rare occasions when I venture that far north, though, I usually stop by The Empanada House on Pleasantville Road. The Empanada House serves a wide variety of its eponymous pastries, which are an excellent alternative to pizza for diners in search of a quick meal.
The menu features meat-filled, vegetarian, and dessert empanadas, both traditional and "fusion". One classic is the beef "Mendocina" empanada, which is filled with ground beef flavored with green olives and red peppers. It's a good introduction to the empanada for carnivores. For vegetarians, the cheese and spinach empanadas are a good gateway to empanada addiction. The humita empanada, filled with ham, corn, and (if one so chooses) cheese, is a bit more of an acquired taste, but I like it. Dessert options are good as well, with guayaba and cheese being a stand-out. While most empanadas cost $3, the Empanada House often runs 2/$5 specials. All empanadas are typically fried, but you can request that they be baked.
If you are looking for a quick, light meal but want an alternative to pizza, check out The Empanada House if you are in the vicinity of Briarcliff Manor.
