What to eat on a Low-FODMAP diet: Upside-Down Quinoa Pizza recipe

I just invented The. Most. Delicious gluten-free, dairy-free, low-FODMAP recipe. I'm calling it Upside-Down Quinoa Pizza. I am eating it now and I love it so much I literally can't stuff it into my face fast enough. Here 'tis:

1.25 cup cooked quinoa
2 large eggs
Juice from 1/2 of a lemon, squeezed
1/2 cup fresh basil, chopped
1/2 tsp paprika
1/2 tsp dried crushed oregano
1 cup diced cooked chicken sausage (you could substitute mozzarella cheese or just try it vegan if you want)
1/2 cup diced zucchini (sometimes I use a full cup if I'm feeling veggie-needy)
salt to taste
Organic crushed tomato sauce (I used about 1/2 cup?)
Big handful of spinach

1. Preheat oven to 350 degrees.
2. Mix together all ingredients except crushed tomato sauce and spinach
3. Spread crushed tomato sauce on the bottom of a 9X9 baking dish
4. Spread chopped spinach over it until the spinach makes a full layer
5. Spread quinoa mixture over that
4. Bake for 45 minutes (until it's browned and solid to the touch on top)

Let me know how it is! I'm also open to suggestions. xo
