I know, World's Best is a big claim, but these chicken tacos are the ones I always come back to. The home cooked Salsa is the key so please don't skimp on that step. So good!
Half-assembling the tacos before serving, i.e. crisping them up in a comal or skillet, means that you'll have to go back to the stove throughout the meal but I think this is totally worth it. A piping hot, crispy tortilla with melted cheese makes these tacos absolutely delicious.
Since people will be folding the tacos as they eat them, it's best to add the beans-cheese-rice layer to only half of the tortilla.
If time has passed and the chicken sitting on the table is getting cold, you can heat it up by adding pieces of it to the tortillas you are crisping up on the stove.
Sometimes I heat up the refried beans in a small saucepan before using them but not always. If using only a thin layer of beans on the tortillas the cheese melting stage can be enough to heat them up.
