In food processor, or by hand, finely dice tomatoes, onion and cilantro.
Gently stir together avocado, salt, and tomato mixture. Distribute filling evenly in a line on bottom third of each egg roll wrapper.
Position a wrapper so a corner is pointing toward you; fold the bottom corner up over the filling. Fold side corners in and roll toward the top corner. Wet the edges of the top corner with a little water. Then fold top corner over and press to seal. Repeat with remaining wraps.
