could you substitute spinach?
and how do you calculate carbs?

You could substitute spinach or chard but would need a lot more since 10 oz of spinach cooks down to about 2 servings. I think this recipe would serve 4.
Most people use www.fitday.com to calculate nutritional values of their recipes. Spinach and chard are zero countable carbs.
