Ingredients and Variations

Mushrooms – Portobellos should be intact without any soft spots. Regular button or baby bellas (creminis) can be used if portobellos aren’t available or you want to make appetizers.

Meat – Besides ground beef, try ground chicken or pork sausage, tofu, or even crab meat. This is a great recipe for using up small portions of leftover meat and veggies as well!

Variations – Switch out cauliflower rice for noodles made from zucchini, spaghetti squash, or sauteed spinach or kale. Or change up the fillings altogether and create a portobello mushroom pizza!

    Recipe is delicious, like all your recipes but I don’t see the fiber content in the recipes. Because I find that determining the exact carbohydrate count that Atkins uses by deducting the fiber is a lot more accurate. Can you supply those in your recipes?
