Ok, this is easy-peasy. Flamenco Eggs from Spain, there’s a similar Mexican version except the first part of that recipe reads
“Robar algunos huevos, pimientos, cebolla, tomates y chorizo” (Steal some eggs, peppers, onion, tomatoes and sausage).....

Red onion and chorizo

Red & yellow peppers

A tin of tomatoes

Eggs in, “lid” on and wait for the whites to congeal. (Is congeal the correct culinary term?

)

Simples!
