In a large bowl, combine the beef mince, pork mince, egg, breadcrumbs, taco spice, oregano, parsley, chipotle salsa and Irish Yogurts Clonakilty Kefir Yogurt. Season well with salt and pepper and mix together until just combined. Avoid overmixing as this can make the meatballs tough.
Roll the mixture into walnut-sized meatballs. You should get around 24 meatballs.
Heat the olive oil in a large frying pan over a medium heat. Add the meatballs and cook for 4-5 minutes, turning regularly until they are nicely browned.
Add the sliced streaky bacon, diced red onion, chopped garlic, diced tomatoes and chipotle salsa to the pan. Season lightly with salt and pepper and gently stir everything together. Continue cooking for 8-10 minutes, stirring occasionally, until the onions have softened, the tomatoes have broken down and the meatballs are cooked through. The tomatoes should reduce just enough to lightly coat the meatballs rather than create a thick sauce.
Meanwhile, prepare the lime yogurt drizzle by mixing together the Irish Yogurts Clonakilty Kefir Yogurt, lime zest, lime juice and a pinch of salt and pepper until smooth.
For the fresh salsa, combine the diced red onion, tomato, cucumber and chopped herbs with the lime juice. Season with salt and pepper and mix well.
Warm the tortillas in a dry frying pan for 20-30 seconds on each side until soft and pliable.
To assemble, spread a little chipotle salsa over each tortilla before adding three meatballs and a spoonful of the tomato and bacon coating from the pan. Top with sliced avocado, the fresh tomato salsa and a drizzle of the lime yogurt. Finish with fresh coriander, pickled jalapeños and grated mature cheddar, if using. Enjoy immediately.
