Preheat the oven to 400°F. Line a baking sheet with parchment paper.
In a shallow dish, whisk together the flour with the Tajin seasoning (optional). In a second shallow dish, whisk together the eggs. Add the breadcrumbs to a third shallow dish.
Pit, peel and slice the avocados into 1/2-inch wedges. Squeeze the lime juice on top of the avocado slices to coat them.
Dredge the avocado slices in the flour mixture, shaking off any excess, then dip them in the eggs and then into the breadcrumbs, coating the avocado slices on all sides.
Arrange the breaded avocado slices on the baking sheet then spray them with cooking spray.
Bake the avocado fries for 10 minutes, flip them once and spray them again with the cooking spray then bake them an additional 10 to 15 minutes until they’re golden brown.
Serve the fries with your choice of dipping sauces.
