Mediterranean Portobello Mushrooms stuffed

Today we are making a Mediterranean-style stuffed Portobellos (vegetarian) that are perfect as appetizer or even a side meal/salad. Typically, I buy my Portobellos at Lidl, usually when on sale. Otherwise they can be quite pricey, compared to other mushroom varieties. They are usually sold in a pack of 3-4 large meaty mushrooms, produced somewhere in Europe (like Poland, Netherlands, etc.).

FUN FACTS: Portobello mushrooms are believed to have originated in Italy. They are actually mature cremini mushrooms, which themselves are a variation of the common white button mushroom. Portobellos gained popularity in the United States during the late 20th century, particularly for their robust flavor and meaty texture.

In Europe, Portobello mushrooms are typically grown in controlled environments such as indoor mushroom farms. Major supermarket chains and grocery stores across Europe often carry portobello mushrooms in their fresh produce sections, somewhat seasonally.
