Place all marinade ingredients in a large resealable bag and thoroughly mix. Add skirt steak into the bag and seal. Mix until the steak is coated in the marinade and place in the fridge for 2-12 hours. The longer it marinates, the more flavor it will get.
Remove the skirt steak from the marinade and pat dry—Grill on a grill preheated to medium-high until it reaches the desired doneness.
Remove from heat and let rest for 10 minutes before slicing. Slice against the grain and use it for tostadas.
Toss tri-color slaw in olive oil. Grill using a grill grid on low-medium heat for 5 minutes or until the slaw mix begins to char slightly, then remove.

Pour oil into a heavy-duty pan until the oil is about 1 inch deep. Heat oil to 350° degrees.
