Instructions
1Brown the ground turkey in a skillet over medium-high, breaking it up, until cooked through, 6-8 min. Season with a good pinch of salt as it browns, then drain off excess liquid.
2Push the turkey to one side, add the chili powder, cumin, paprika, garlic powder, and oregano to the bare pan and let them bloom in the fat 30 seconds, then stir into the turkey with a splash of water. Simmer 2-3 min. Off the heat, squeeze in a little lime juice and taste for salt before building.
3While the turkey simmers, make the corn: melt the butter in a skillet over medium-high and cook the corn until it picks up a little char, 4-5 min (or microwave 4-5 min for the fast route). Off the heat, stir in the lime juice, cilantro, and a pinch of salt.
4Warm the tortillas (30 sec in a dry skillet or wrapped in a damp towel in the microwave).
5Build the tacos with turkey, cheese, lettuce, tomatoes, avocado, and sour cream, with lime wedges to squeeze over. Serve the cilantro-lime corn on the side.
