That humble little can is packed with umami flavor. Try this: Sauté onion in a little coconut oil. When the onion is tender and translucent, add a crushed clove of garlic and cook for 30 seconds, then add a tablespoon or two of tomato paste, frying it in the oniony, garlicky oil for a minute.
Then add whatever seasonings you like – chili powder + cumin or ginger + Chinese five-spice powder, or Lebanese Seven-Spice Blend – and crumble in ground meat. Cook ’til browned, place on top of a pile of veggies, and chow down.
