When purchasing roasted red peppers, you can buy the basic roasted reds stored in water or the roasted reds stored in olive oil and garlic.
Tip of the day: Always use the ones in oil & garlic!
The marinade brings a rich hearty flavor to the red peppers and the difference in calories is minimal. Many of the water stored versions actually have a recommendation on the bottle that suggests a marinade of garlic and oil before using – so buying the marinated peppers does the work for you! Also, with the brands I’ve tried, the garlic is subtle so you won’t walk away with scary breath, just great flavor.
