(I’ll just head straight to the beef stir fry) a very quick and easy method

Heat vegetable oil in a pan or over medium heat cook and stir beef with garlic, ginger onions until brown and almost tender(add little water). In another pan heat little veg oil, add vegetables, onion, ginger and garlic and stir fry

Stir beef into vegetables and add soy sauce, and seasoning to taste Continue to cook and stir until vegetables are a bit tender and beef well cooked.

Cut watermelon in halves, remove the back(no need to take out the seeds) blend with ginger (and even mint leaves if you like) sieve and then refrigerate and enjoy ! Bon apetit !
