We doubled the avocado and corn and put the corn on the BBQ. It comes out great that way (though hand picked would have had more flavor, if we could have found it). The lime and avocado are musts, but I think some roasted poblanos or homemade tomatillo salsa would make these tacos even better.
Simple and easy, and a different twist on a taco from what we're used to. Wholesome plain ingredients and a fresh flour tortilla made a light, colorful lunch enjoyed in the autumn sunshine on our back patio. Very nice!
