For Pho with Beef and Colorful Vegetables, first put the bones in a large pot with the leg slice or soup meat, onions, ginger, cinnamon and crushed peppercorns. Add enough water to cover all the ingredients.
Bring the water to a boil and simmer the soup over low heat for at least 4 hours, skimming the fat from the surface occasionally.
Season the soup with the salt, pour through a sieve into a preheated large soup bowl and place on a warming plate on the dining table.
Place the fish sauce, chilies, and fruit fillets in small bowls. Arrange the remaining vegetables, bean sprouts and beef on a serving platter.
Cook the noodles according to package directions, drain briefly, and transfer to a large bowl.
Place bowls and dishes around the soup bowl with the hot soup on the table. Pour some of the soup into each of the bowls and add noodles, meat and vegetables in small amounts to taste. Let stand briefly and enjoy Pho with beef and colorful vegetables.
