Once upon a time I lived in Colombia for a year. This was my favorite breakfast there. Serve with buttered toast and cafe con leche (coffee with hot milk). This recipe duplicates that taste memory for me. I once had this with some chopped fresh spinach leaves sauteed with the vegetables, and that was very nice, but that is not how it is normally served. You can use diced yellow onion instead of the green onion if you prefer.
