Pat chicken breasts dry and season both sides with salt, pepper, and lemon juice.
Melt butter in a large skillet over medium heat.
Add chicken and sear until golden on both sides.
Remove chicken to a plate and set aside.
In a bowl, whisk together cream, mustard, complete seasoning, salt, pepper, and milk.
Stir in the chopped fresh cilantro.
Pour the sauce into the same skillet and bring to a gentle simmer.
Return chicken to the pan and cook 10 minutes until fully done and sauce thickens.
Tip: Scrape the browned bits from the pan into the sauce for extra flavor.
