Heat the oil together with the cooking spray in a deep, large pot over medium heat for a few seconds. Add the leeks and onions; stir and lower heat. Cook until the leeks and onions start to brown, stirring occasionally. Add garlic and a few drops of water as needed; the mixture will start to brown. Cook another few minutes, scraping the bottom of the pan so that nothing sticks.

Add ground veal and soup powders. Stir until the meat browns and add the spinach. (It is not necessary to defrost, but it should be broken up.)

Add water. Bring to a boil. Lower heat and simmer for 30–35 minutes. Add salt and pepper to taste.
