For the lowest possible carbs, reduce or omit the tomatoes and onion or use them only as a garnish while increasing lettuce and avocado. You can swap ground turkey for ground beef or chicken, keeping the same seasoning amounts, and adjust the oil only if using very fatty meat. To meal prep, store the cooked taco turkey separately from the chopped lettuce and toppings, then reheat the meat gently and assemble the salad just before eating so the greens stay crisp. Add extra cheese, avocado, or a drizzle of olive oil if you need to boost the fat content to fit your keto macros.
