Low Carb Steak Fajitas


Fajias is a Tex-mex (Texas-Mexican) food, originally made with steak. Typically skirt steak with bell peppers and onions served in a flour tortilla, but of course we skipped the tortilla to make it keto ๐Ÿ‘ If you don’t know what to serve at your next dinner party.. Well.. Now you know! ๐Ÿ˜‰ This low carb steak fajitas is incredibly easy to make, but looks both fancy and tasty!

It has become more common to use chicken when making fajitas, but feel free to use the protein source you prefer. Steak, chicken, scampi, fish – they will all work! Or tofu if you want to make it vegetarian. The spices used are normally chili, onion, garlic, cumin, paprika and sugar. We are avoiding the sugar (obviously ๐Ÿ™ƒ), but you can add some erythritol if you want to make it sweeter.
