Take a large cutting board and start grating the carrot, slicing the onion, and mincing the garlic.
Divide from the broccoli all florets and cut the mushrooms.
Mix the soy sauce with vinegar in a small bowl, and set aside.
In a large non-stick skillet, at a medium to high heat, add the garlic with onion, and cook a maximum of 1 min until soft and slightly brown.
Add the broccoli, carrot, and mushroom, and cook for 7-10 minutes or until the veggies turn brown and look juicy.
At this point, add the mixture of soy sauce with vinegar and cook no more than 1-2 minutes.
Take a platter and pour all the veggies. Sprinkle sesame seeds on the top.
Enjoy!
