Make the filling: Place cream cheese in a large microwave-safe bowl. Warm for 30–60 seconds on medium power until softened.
Stir in green salsa, lime juice, cumin, chili powder, onion powder, garlic salt, cilantro, olives, and green onions. Add shredded chicken and cheese, mixing well to combine.
Assemble the taquitos: Heat oven to 425°F. Line a baking sheet with parchment or foil (avoid silicone mats—they trap steam and soften the bottoms).
Warm tortillas so they’re soft and pliable.Flour tortillas: room temp or 15–30 seconds in the microwave.Corn tortillas: must be warmed or they’ll crack. Scoop about ¼ cup filling onto the lower third of each tortilla, leaving space from the edges. Roll tightly and place seam-side down on baking sheet.
Lightly spray or brush with oil and sprinkle with a pinch of kosher salt.
Bake: Bake 15–20 minutes until crispy and golden brown. Keep an eye after the 10-minute mark—tortillas vary in crisping. Once edges are browned and some filling begins to peek out, they’re ready.
Cool slightly and serve warm.
