Tomatoes are high in potassium, meaning tomato sauce is usually off limits for someone managing kidney disease on a low potassium diet. This kidney-friendly sauce replaces half the tomatoes with roasted red peppers for a lower potassium sauce that can be used on pasta, pizza, or as a replacement for tomato sauce in recipes. And, it tastes great! You can use store bought roasted red peppers (look for the lowest sodium option) or roast red bell peppers at home. You can easily double or triple this recipe to make a larger batch and freeze some for later.

This recipe has been approved as kidney-friendly by DaVita dietitians who believe a kidney-friendly diet can be both nutritious and flavorful. Enjoy!
