When I served this sauce to my husband, he thought it was an extra tasty marinara. And while I like marinara, the carbs in tomatoes really do start to add up, making this red pepper sauce a better option!
The great news is that this sauce is super easy AND can be prepared in advance! For this recipe I've used roasted red peppers from a jar - they're so convenient and I love their vibrant color and the char marks! But of course you could always roast your own like I did for my Roasted Red Pepper and Buffalo Mozzarella Salad!

How to Make a Low Carb Roasted Red Pepper Sauce
Add the roasted red peppers, garlic paste, dried oregano, tomato paste, red wine vinegar and salt and pepper to a small blender (I use an attachment on my stick blender).
Blitz until a sauce has formed. Taste for seasoning and adjust as necessary.
Transfer the sauce to a bowl, cover, and store in the fridge until required. This sauce would actually make a fantastic low carb salsa! However you might like to reduce the garlic if you intend to serve this sauce uncooked.
When you're ready to cook, pour the sauce into a small saucepan and warm through, letting it reduce just a little.
Serve over cooked chicken, pork, or fish. Shown below with some baked tilapia and delicious spinach Miracle Noodles - only 2g net carbs for the whole 3oz bag!).
