"She warmed up a fresh tortilla to serve as the base for her burrito."
A flat round bread made out of cornmeal or flour. In Mexican cuisine they are often served with a filling or topping such as frijoles "beans", carne "meat", salsa "sauce", sour cream and cheese; in the latter case they are called quesadillas.
"She warmed up the tortilla before adding beans, meat, and salsa to make her favorite taco."
The word comes from Spanish, where it originally meant a small cake or flatbread.
