Pat the chicken tenders dry with paper towels. Cover a large cutting board with a sheet of cellophane (plastic wrap).
Arrange half of the chicken tenders on the covered board in a single layer, spacing them evenly. Cover the chicken with another sheet of cellophane.
Using the flat side of a meat mallet, gently pound the chicken through the top layer of cellophane until each piece is about 1/4" to 1/3" thick. Do not over-beat so the chicken falls apart. Remove and keep the top sheet of cellophane for the next batch.
Remove the top sheet of cellophane and lightly sprinkle the pounded chicken with salt and pepper. Repeat steps 2–4 with the remaining chicken and the saved sheet of cellophane.
In a medium bowl, whisk together 2 large whole eggs and 1 tablespoon mayonnaise. Add 1 tablespoon all-purpose flour, 3 tablespoons milk, 1/2 teaspoon Mrs. Dash seasoning, and 1/8 teaspoon salt. Whisk until well blended; this is your egg wash.
In a second medium bowl, combine 2 cups Italian bread crumbs and 3 tablespoons flour. Mix to blend evenly.
Pour canola oil into a large, heavy-bottomed skillet to a depth of about 1/4". Heat the oil over medium-high heat until it is hot enough that the chicken sizzles when added.
Working in batches (do not crowd the pan), dip a chicken tender on both sides in the egg wash, then press it into the bread crumb mixture until evenly coated. Place coated tenders on a plate while you finish coating the rest.
When the oil is hot, add about 4 coated chicken tenders to the skillet and sauté about 4 minutes per side, or until golden brown and cooked through.
Use tongs to transfer cooked tenders to a plate lined with paper towels to drain. Repeat frying with remaining tenders.
Let the tenders rest on the paper towels a minute or two before serving.
