Ingredients & Nutrition

Nutrition
I was shocked when I analyzed the nutrition of this recipe. It is incredibly nutritionally dense, and balanced.
At around 7 grams of protein per serving, the dish is not a high protein meal but provides complete amino acids thanks to the the three sisters beans, corn, squash along with quinoa. You can add pumpkin seeds to boost the protein significantly.
Squash and beans give the dish impressive levels of vitamin A, vitamin C, magnesium, potassium and folate. These nutrients support immunity, nerve function, metabolism and healthy red blood cells.
Quinoa, beans and the squash together contribute a broad B vitamin profile including B1, B2, B3, B5 and B6, which help convert food to energy and support healthy brain function. Folate is particularly high at around 35 percent of daily needs per serving.
While total fat is low, the fats present are mostly polyunsaturated omega 3, mostly from quinoa and beans.
The squash, tomato and spices contribute carotenoids like beta carotene and phytonutrients that have anti inflammatory and antioxidant properties.
