I will be cooking for a group of friends this weekend and hope to introduce them to 'real tacos.' My original hope was to make tacos el pastor, but a few of those who I will be cooking for cannot eat pork. Instead I'm hoping to make beef or chicken tacos. I'm looking for something traditional. I have considered Tiga Poblano and Beef tongue tacos(surprisingly I introduced this to my friends and they enjoyed it!). Many thanks and feel free to post any pork recipes that are awesome, I would love to have those for the future.
