What are the fundamental components of the rustic dish known as papas a lo pobre?

Fried potatoes, onions, and peppers traditionally slow-cooked in olive oil.

Papas a lo pobre, or 'poor man's potatoes,' represents a hearty, rustic dish emphasizing simple, quality agricultural ingredients that are slow-cooked to richness. The foundation of this preparation consists primarily of potatoes, onions, and peppers. These elements are slowly cooked, often submerged or generously coated, in olive oil until they achieve a tender texture that absorbs the flavors imparted by the slow rendering process, sometimes incorporating seafood elements but fundamentally remaining a dish centered on the fried vegetables.
