Pat the chicken tenders dry with paper towels. Place a large cutting board on the counter and cover it with plastic wrap or cellophane.
Arrange half of the tenders on the covered board spaced evenly and cover them with another layer of plastic wrap.
Use the flat side of a meat mallet to gently pound the chicken to about 1/4"–1/3" thickness; do not over-beat so the meat stays intact.
Remove the top plastic layer, lightly season the pounded tenders with salt and pepper, then repeat the flattening process with the remaining tenders.
In a medium bowl, whisk together the eggs and mayonnaise until smooth. Add 1 Tbsp flour, milk, Mrs. Dash, and 1/8 tsp salt and whisk until blended to make the egg wash.
In a second medium bowl, combine the 2 cups Italian bread crumbs with 3 Tbsp flour and mix well to make the breading.
Pour canola oil into a large heavy-bottomed skillet to a depth of about 1/4" and heat over medium-high until shimmering; the oil should sizzle when a breadcrumb is added.
Working in batches, dip each chicken tender first into the egg wash, coating both sides, then press into the bread crumb mixture until evenly coated. Place coated tenders on a plate while you heat the oil.
Fry about 3–4 tenders at a time without crowding the pan. Cook approximately 4 minutes per side, until golden brown and cooked through (no longer pink in center).
Transfer cooked tenders to a paper towel-lined plate to drain briefly before serving.
