Taco Night at Los Lemleys

Tacos (or Tex-Mex) aren't common in Peru, but Tex-Mex is a cuisine that John and I LOVE! At least once a week, we make something at least semi-tex-mex: black bean or refried bean burritos, tacos, fajitas, quesadillas with whatever we have in our cupboards or 'frig'.
A couple of weeks ago, John shared his chili with Maximo. I was waiting for the "fallout" (literally) from Maximo scarfing down a bunch of black beans, but there wasn't one, so we've given him beans a few times since. He's picky about his beans - not the red kidneys, the cute black ones.
When I was a kid I loved taco night. It wasn't super often that we had taco night, but it was so much FUN! I felt so big assembling my own tacos in whatever proportions I wanted - they were always heavy on the cheese. I loved the electric skillet my mom used to brown the meat in and the soup bowls filled to the rim with diced tomatoes, shredded lettuce, cheddar cheese, salsa and sour cream. Fond traditions and family memories like this always make me wonder what Maximo is going to find special and hold dear to his heart as he grows older.
So, tonight, while we ate our tacos, Maximo ate/smeared/threw quite a large quantity of guacamole, tortilla, black beans and ground beef. Here's the evidence.

An eating utensil? What do I need this for?

And a bit of water to wash it all down with - and start the pre-wash of his clothes
