This low carb version of pepper steak and onions is full of colorful peppers, tender beef  and a sauce with no refined sugars.  You can easily cook it in a skillet on your cooktop.


  • 1/3 cup low sodium soy sauce
  • 3 tablespoons vegetable oil *
  • 3 tablespoons sugar substitute ( I used Swerve brown sugar)
  • 4 peppers, (I used a combination of red, yellow & green),  cut into strips
  • 2 yellow onions, sliced
  • 4 cloves of garlic minced or 2 teaspoons ground garlic
  • 2 teaspoons ground ginger
  • 4 tablespoons rice wine vinegar
  • 1/4 cup of  low sodium beef broth or diluted brown gravy mix
  • 2 lbs.of top round, stew beef or flank steak, sliced thin against the grain. **
  • salt and pepper to taste
  • cherry tomatoes-optional


  1. Mix the soy sauce, beef broth or 2 tablespoons brown gravy mix with 1/4 cup water.  Add in the vinegar, sugar substitute, garlic and ginger.  Set aside.
  2. Heat a few teaspoons of oil in a large skillet and cook the onions until they are very lightly browned about  3-4 minutes. Remove from pan.
  3. Add another two teaspoons  of oil and cook the peppers until they are softened a bit but are not soggy.  You want them to maintain their color and still have a touch of crunch.  Set them aside as well.
  4. Heat a bit more oil and sauté the beef until cooked and no longer pink, about 6-8 minutes.
  5. Add the sauce to the beef, salt and pepper to taste. Bring to a simmer .  Add the onions, peppers and optional cherry tomatoes  to skillet and stir to heat through.
  6. Serve with cauliflower rice.


*If the skillet is getting a little dry as you are sautéing the meat or vegetables, add a bit of water rather than more oil.  

**I always trim off any additional fat on the beef.  It will lessen the calories, but not the flavor.
