Mwanza locals often call tilapia "sato" rather than the standard Swahili term, a nickname specific to the Lake Victoria region.
A whole tilapia, called sato around Mwanza, is grilled over charcoal, then coated in a garlicky coconut sauce brightened with lime and chili. It's a favorite lakeside meal sold at fish stalls near Mwaloni Market and at restaurants overlooking Lake Victoria.
