Have you tried microgreens?

Microgreens are young, nutrient-dense seedlings of vegetables and herbs, harvested 7-21 days after germination at the cotyledon stage (usually 1-3 inches tall). Packed with vitamins, antioxidants, and intense flavor, they are often called "vegetable confetti" and are used to add color, texture, and nutrition to salads, sandwiches, soups, and as garnishes.

Nutritional Value and Health Benefits
Highly Nutritious: Microgreens can contain up to 40 times more nutrients (vitamins, minerals, antioxidants) by weight than their mature counterparts.
Health Benefits: Potential benefits include aiding in the prevention of chronic illnesses, supporting heart health, improving cognitive function, and managing Type 2 diabetes.
Nutrient Profile: They are rich in vitamins C, E, and K, as well as carotenoids

i am generally a sprouter rather than a micro-greener. microgreens are expensive. tastewise theyre not that great, theyre supposed be great nutritionally so if i was going to go to the expense of making microgreens id use them in smoothies
