Health Benefits and Nutrition Facts
Portobello Mushrooms
Portobello mushrooms are low in calories but rich in important nutrients such as selenium, potassium, and antioxidants. They support immune health and may help fight inflammation.
Quinoa
Quinoa is often called a “super grain” and for good reason. It’s a complete protein, which means it contains all nine essential amino acids. In addition to protein, quinoa offers fiber, iron, magnesium, and other key nutrients that help support heart health and digestion.
Ground Beef
Using lean ground beef adds high-quality protein and important vitamins like B12 and zinc. Choosing lean cuts with less fat helps reduce saturated fat intake while still adding flavor to your meals.
Spinach
Spinach is a leafy green packed with iron, calcium, and vitamins A, C, and K. It’s excellent for bone health, vision, and immune support.
Precautions
If you’re watching your sodium intake or managing cholesterol, consider using low-sodium cheese or reducing the amount of added salt. Also, ensure the ground beef is well-cooked to avoid any risk of foodborne illness.
