Make the pickled red onions, if using. Place all of the ingredients in a medium bowl or glass jar and let them sit at room temperature, stirring once or twice, while you make the ground pork.
1 cup thinly sliced red onion, 2 Tablespons lime juice, 1 Tablespoon red wine vinegar, 1 teaspoon kosher salt, 1 teaspoon granulated sugar, honey, or agave
Heat the olive oil in a large skillet over medium heat. Once it’s hot, add the onion and cook, stirring frequently for 2-3 minutes, until soft and translucent. Add the minced garlic and cook for another 1-2 minutes, until fragrant.
1-2 tablespoons olive oil, 1/2 small yellow or red onion, 2 cloves minced garlic
Push the onion and garlic to the side and place the ground pork in the pan. Use a meat smasher or spatula to break the pork up into small bits. Continue to cook, mixing the pork with the onions and garlic, until no pink remains.

When the pork is almost done, let it sit in the hot pan, without stirring, for 2-3 minutes so the pork crisps, then stir and repeat 1-2 more times until it's as crispy as you'd like it. Be careful not to crisp it too much or it will end up tough and chewy.
Turn the heat down to medium-low and add the seasoning and honey and continue to cook until completely combined.
