In a pan on the stove, cook the meat (if using) in 1 tbsp of olive oil until brown, then drain the excess oil, remove the meat and set it aside.
Add the remaining 1 tbsp of olive oil to the pan and sauté the onion and garlic until fragrant.
Add in the marinara sauce, spices, broth and meat and stir together with the onions and garlic.
Turn the heat up to bring the soup to a boil. Once boiling, add in lasagna noodles, breaking them into large pieces as you add them.
Keeping a close eye, stir until noodles are tender. Once they're cooked, add in the spinach and turn off the heat.
If you're using both ricotta and mozzarella, mix together the cheeses.
Add the soup to a bowl and top with a scoop of the cheese mixture. Top with fresh basil if you wish!
