Chips Mayai (Tanzanian Chip Omelette)

Chips mayai is chips set into an omelette and cooked as a single flat cake. The name is literal, chipsi is chips, mayai is eggs in Swahili, and it is one of the defining Tanzanian street foods, also known as zege. It is sold from stalls across the country and cooked to order: fries already made, eggs beaten with chopped onion, tomato, green pepper and coriander, the two combined in a hot pan and turned once. Minced meat goes in where a heartier version is wanted. It arrives with kachumbari, the East African tomato and onion salad, and tomato sauce. The comparison the source draws with Spanish tortilla is apt and worth thinking about, because the difference is instructive. A tortilla española uses potato sliced thin and cooked gently in oil until soft, folded into egg and set slowly into something dense and custardy. Chips mayai uses chips, already fried, already crisp, and cooks fast, so the potato keeps some of its structure and the egg stays lighter. Same two ingredients, entirely different results, and the potato cut is what does it. It is eaten at any hour: breakfast, a late-night meal after drinking, or a snack in between. Nothing about it is formal.
