For the shaken beef: Place the beef in a bowl with the garlic, onion, liquid seasoning, sugar, fish sauce and pepper and mix well. Heat a large heavy-bottom pan over medium-high until very hot. Add the butter or oil. Add the beef cubes shaking the pan to coat the meat with the butter or oil. Cook, turning the meat with tongs until browned and seared on the outside but still pink in the center, 3 to 4 minutes (or cook to desired doneness). Add the Cognac and toss the beef before removing from the heat.
For the watercress salad: Lightly roast the shallots in a dry saute pan over medium heat until light browned and fragrant, about 5 minutes. Whisk together the rice vinegar, garlic, fish sauce and honey in a bowl. Lightly toss the watercress and shallots with the dressing. Season with pepper.
Arrange the sliced tomatoes on plates to make a decorative base. Arrange the watercress around or on top of the tomato slices. Place the beef in a mound on top of the tomatoes and watercress and serve with the rice.
