cut the zucchinis, garlic and onion in very small cubes (it will cook faster), set aside
cook ground beef in a wok or big skillet with a little olive oil, I like it a bit brown then set aside
In the same skillet were you cook the beef , sprinkle olive oil, first cook the onions and garlic on low fire until onions and garlic are transparent, when they are add the zucchini, a teaspoon of mustard and a teaspoon of currypowder, sprinkle with salt and pepper. Cover the zucchini and let cook for approximately 15min or until zucchinis are soft.
When the zucchinis are cooked mix in the cooked ground beef and stir a bit so that the flavors mix together, you could add coriander or shiracha to make it spicier.
remove the romaine leaves from the lettuce heads and serve the zucchini/grounded beef mixture in the romaine leaves.
Drizzle with shiracha and shredded cheese
Enjoy!!
