To make these bowls, start with the potatoes since they take the longest. Preheat your oven to 425°F. Wash your potatoes and cut them into halves or quarters, then rinse and dry them thoroughly — the drier they are, the crispier they'll get!
Add them to a large bowl and toss them with the olive oil, garlic powder, baking soda, salt, and pepper until evenly coated. Spread them into a single, even layer on a baking sheet and transfer them to the oven.
Bake the potatoes for 25 minutes, then give the pan a good shake and bake for another 15–20 minutes, until they are golden, crispy, and absolutely irresistible.
While the potatoes are in the oven, prepare the ground turkey. Heat a teaspoon of olive oil in a large skillet over medium heat. Once the oil is hot, add the ground turkey and taco seasoning, breaking the meat down into small pieces as it cooks. Cook until the turkey is fully cooked through, then remove it from the heat and set it aside.
Next, make the jalapeño lime yogurt sauce. Add the Greek yogurt, jalapeño, cilantro, shallot, garlic, lime juice, and kosher salt to a small blender and blend until completely smooth and creamy. Taste and adjust the seasoning as needed.
Once everything is ready, it's time to assemble your bowls! Start with the crispy potatoes on the bottom, then top with the seasoned ground turkey. Add the shredded iceberg lettuce, halved baby tomatoes, shredded cheddar cheese, and pickled onions. Finally, drizzle a generous amount of that jalapeño lime yogurt sauce over the top and enjoy immediately!
