Preheat your oven to 350 degrees.
In a pan on the stove over medium to low heat, sauté onion and garlic together with oil and then add in the kale/spinach and zucchini.
Add in spices then top with the crushed tomatoes and stir together. Simmer for 5-10 minutes.
Mix together tapioca starch and either water, veggie broth or bone broth to form a paste, then quickly stir into the skillet. This will thicken the tomato sauce slightly.
Crack the eggs on top and move the skillet to the oven to bake for 10-15 minutes or until eggs are cooked.
If you'd like, top with avocado, fresh herbs, salt and pepper and serve with (for paleo, grain free) tortillas or pita bread!
