You could use corn tortillas rather than flour if you'd prefer. If so, warm them slightly to make them less likely to tear when rolled***

Pregeat the oven to 350°F. Line a large baking tray with foil and grease it lightly. Set it aside. In a medium bowl, stir the softened cream cheese, salsa and shredded cheese together. Add in the seasonings and taste. Adjust to suit your tastes as needed. Stir in the cooked chicken and onion and stir to incorporate everything.

Lay out one tortilla at a time and place about 2 tbsp. of chicken mix onto the center, in a line. Repeat until there is no more mix left.

Tightly roll up the tortilla and place on the baking tray, seam side down. Lightly brush olive oil over the top of the taquitos. Bake for 12-14 minutes, or until they begin to brown slightly. Let them cool slightly, then serve.
