LU: Bell Peppers are like tomatoes. They start out green and slowly turn red (or other colors).
From the website of the Centers for Disease Control and Prevention:
“Bell peppers can be found in a rainbow of colors and can vary in flavor. The variety of the pepper plant, and the stage of the ripeness, determines the flavor and color of each pepper. For example, a red bell pepper is simply a mature green bell pepper. As a bell pepper ages, its flavor becomes sweeter and milder. Red bell peppers contain eleven times more beta carotene than green bell peppers.”
