Make the Mexican spice blend: In a medium bowl, combine the chili powder, light brown sugar, cumin, coriander, cayenne, paprika, oregano, onion powder, and garlic powder.
Make the Mexican pulled pork: Season the pork generously with salt and pepper and rub all over with 2 tablespoons of the Mexican spice blend.
Add the olive oil to a multicooker and set it to the cook function.
Once the oil has heated, add the pork and brown on all sides until golden, 3 to 4 minutes per side.
Add the chicken stock.
Cover.
Switch the function to slow cook and cook on high for 5 hours or on low for 8 hours, until the pork is fork tender.
Transfer the pork from the multicooker to a large bowl.
Allow to cool slightly.
Pour the liquid from the multicooker into a separate bowl.
Shred the pork with two forks, discarding any excess fat.
Add the reserved liquid a little at a time to moisten the pork.
Taste and adjust the seasoning, if necessary.
Keep warm until ready to serve.
Next, make the peppers and onions: Set the multicooker to the cook function.
Add the olive oil, onion, and bell peppers.
Cook until the vegetables are tender and slightly charred, 10 minutes.
Season with salt and black pepper.
Transfer to a serving platter.
Meanwhile, make the chipotle-lime crema: In a blender, combine the sour cream, chipotle, lime juice, olive oil, honey, cilantro, and salt.
Blend on low until combined.
Transfer to a serving bowl and refrigerate until ready to serve.
Make the charred corn salad: Heat a grill to medium-high or heat a grill pan over medium-high heat.
Add the corn and grill on all sides until slightly charred.
Remove from the grill and let cool.
In a medium bowl, combine the serrano pepper, scallions, cilantro, lime juice, and olive oil.
Cut the corn kernels off the cobs and add them to the bowl.
Toss to combine and season with salt and black pepper.
Set up a buffet-style table with the Mexican pulled pork, peppers and onions, charred corn salad, chipotle-lime crema, avocado, queso fresco, pico de gallo, lime wedges, and flour tortillas.
Invite everyone to DIY their own fajitas.
Notes / Tips / Wine Advice:
If you are using a traditional slow cooker instead of a multicooker, you can brown the pork and cook the peppers and onions in a sauté pan on the stovetop.
Any extra Mexican spice blend can be stored in an airtight container for up to 6 months.
