Romesco sauce doesn't get any easier than this. While the traditional version is made with oven-roasted tomatoes and red peppers, this version uses a few shortcuts with delicious results.
In a high-speed blender, combine the roasted red peppers, almonds, garlic, vinegar, paprika, crushed red pepper flakes (use only ¼ tsp for a mild sauce), olive oil, parsley, salt, and water. Secure the lid and blend until the mixture is smooth.
Taste and adjust any seasoning, as needed. You can add up to ¼ teaspoon more salt for extra flavor, or more red pepper flakes for a spicier kick. Transfer to an airtight jar and store in the fridge until you're ready to use it. You can store this sauce in the refrigerator for up to 5 days.

Ensure there's no added sugar in the jar, as this can alter the flavor. One cup of roasted red peppers weighs approximately 8 ounces, if you prefer to measure with a scale.
