A salad would be an example of a heterogeneous mixture. This is because a salad is not made up of the same exact greens or toppings.
There is typically a mix of lettuce and other vegetables like kale and spinach, as well as nuts, cheeses, croutons, and even fruit. An example of a homogeneous mixture would include a container of salt or pepper. If these two containers were to mix their contents, they would become a heterogeneous mixture.
A few properties distinguish something to be a heterogeneous mixture. Included in this are mixtures that do not evenly mix, have more than one phase, particles are not uniformly distributed, and it is easily seperated physically. Some examples of these types of mixtures includes salt and pepper, cereal, rocks, and a mixed bag of candy.
Another example of a heterogeneous mixture is a salad. In a salad the components do not mix into one another. Even though they mix to make up a whole they retain their own set of properties and can be easily separated from one another.
