Salt and pepper the chicken tenders. Then dredge in flour and set aside.
Heat 2 tablespoons of olive oil in a large skillet over medium high heat. Once the skillet is hot and the oil is shimmery, add half of the chicken tenders.
Cook the chicken, turning as needed, until until the tenders are golden brown and cooked through, about 5 minutes. Transfer to a bowl or plate. Repeat with the rest of the tenders.
Wipe out the skillet to remove all the dark brown flour. Reduce the heat to low.
Add the remaining tablespoon of olive oil and the shallots and garlic. Cook until the shallots are soft, 1-2 minutes.
Add the tomato paste and cook for 30 seconds.
Increase the heat to medium high and add the wine. Bring to a boil and cook down until reduced by half, about 2 minutes
Add the chicken stock, oregano, and mustard. Bring to a boil. Boil for 5 minutes.
Add the evaporated milk and bring back to a boil to let the sauce thicken a little.
Then reduce the heat and stir in the parmesan. Once it's melted, add in the artichokes and heat them through.
Add back in the chicken and warm it up (about 30 seconds). Then sprinkle in the parsley and serve.
