In a large pot, add 2 tablespoons of water or oil. Then add in the diced white onion and minced garlic along with the tomato paste and spices. Sauté over medium heat until translucent, about 3 minutes.
Using the same pot, add in the tomato sauce as well as the white beans.
Let everything simmer for about 7-10 minutes.
After, add in the cherry tomatoes followed by the spinach. Cook for a few minutes more or until the spinach has wilted.
Remove the pot from heat and divide into serving bowls. Serve with gluten-free bread, potatoes or rice. Enjoy!
Notes
Feel free to swap out the spinach for any other leafy green of your personal preference. For example, kale or swiss chard both work great for this dish too.
