Season pork chops with salt, pepper, garlic powder, onion powder, and Mrs. Dash.
Heat oil over medium-high heat & brown chops.
Thinly slice onion while chops brown.
Place pork chops into preheated crockpot.
Cook onions with a little salt & pepper over medium-low heat for about 12 minutes (until light-brown & cooked through).
Add 2 Tbsp minced garlic & 3 Tbsp rice flour. Stir until flour is moistened.
Cook over low heat for about 2 minutes.
Add 3/4 cup of dry white wine and 2 Tbsp apple cider vinegar.
Stir and cook until your onion sauce starts to thicken.
Pour into crockpot over pork chops.
Cook for 6-8 hours on low or about 4-5 on high.
Remove pork chops when fork-tender, leaving as much of the sauce as possible.
Add 2 Tbsp of Dijon mustard and 1/2 cup heavy whipping cream. Stir well.
Pour sauce over the chops on the serving plate or on individual plates.
