It’s a vegetable stew that uses seasonal Mediterranean fresh vegetables like peppers, onions, tomatoes, zucchini and/or eggplant, simmered in olive oil. Pisto Manchego is often compared to the famous French Ratatouille and for an obvious reason; these dishes are pretty similar. As a matter of fact, Pisto Manchego is often called ‘Spanish Ratatouille’. However, some Spaniards would argue that Pisto preceded Ratatouille, which apparently traveled from La Mancha, to Basque county, and finally to France.
