The main RuneScape Wiki has an article on: Spinach roll
The Old School RuneScape Wiki also has an article on Spinach roll.

A Spinach roll is a piece of food that can be obtained by using a Crystal key on a chest in Taverley, by killing Moss giants, or by smashing Strange Barrels. When eaten, the player is healed 2 Hits.

Spinach rolls used to be a popular scam item, with some players selling them for inflated prices in banks, incorrectly advertising them as "rare". This is most likely the reason they are not tradable in RuneScape 2 and RuneScape 3.
