Prepare all of the ingredients.
Place pork into slow cooker. Combine remaining pork ingredients and pour over pork. Secure lid and cook on low for 5 and a half hours.
In a mason jar, combine dressing ingredients (grapefruit, vinegar, oil, honey, salt, miso, onion powder, sesame seeds, and garlic powder). Secure a lid to the jar and shake the heck out of it. In a larger bowl, combine coleslaw mix, radishes, and onions. Pour dressing over top of veggie mix and toss to coat. Place in refrigerator until ready to serve.
Remove pork from slow cooker and shred. Return to slow cooker and stir with juices. Replace lid and let cook 30 minutes more.
On a griddle or flat top, warm up tortillas for 2-3 minutes on each side.
Build the taco: Place a portion of coleslaw on bottom of tortilla, top with a portion of the pork and sprinkle with crispy wonton strips.
