1. 🧐What You Need to Know About Microgreens?

1.1 Definition of Microgreens

Microgreens are young, nutrient-rich versions of leafy greens and other vegetables, typically harvested 1-3 weeks after germination. With a wide variety of plant species, including different plant families, microgreens come in a range of flavors, textures, and nutritional benefits, making them versatile for many different dishes.

They are a great source of fibers, essential minerals, vitamins, and antioxidant compounds. Among these species, fava bean stands out due to its nutritional benefits and flavor variety, enhancing dietary diversity and nutrient intake.

Microgreens are normally consumed raw and can be used to prepare salads, appetizers, and sandwiches or to accompany any meat or fish dish.
