I adore Navajo Tacos! Ironically, they are a post colonial invention that was the result of the US forcing the Navajo into concentration camps and issuing them rations of flour, sugar, and lard. The Navajo people invented fry bread with their limited ingredients, which became the base for many other foods later on.
I use a budget app for tracking income and spending on a transaction basis and then keep the rest of my finances in spreadsheets.
