What's the cost of lunch in cheap cafes/market?

I'm in Ensenada now,and a small horrible lunch in ANY cafe here costs at least 80 pesos(4.60 USD)I used to live in Mzt and remember the food was good and cheap. I plan to move there and eat at "go native greasy spoons" most of the time(never would be on Trip Advisor)If anybody knows the price of comida corrida there please lemme know, thanks!

Comida corrida in Coatepec, Veracruz is 50 pesos in several places. Taco stands and the counters in the market  cost less.

In La Peñita de Jaltemba,  comida corrida varies from 40 to 50 pesos.

Adios, GyC.
