Any number of variations. Use whatever fruit is in season and whatever nuts are on sale. Dried fruit is also fine.
To toast the nuts: Spread them in a single layer on a plate and microwaving them on high for three minutes. This is the easiest, most reliable way to toast nuts, which improves the flavor and texture immensely for salad.
You can also toast them in the oven in a single layer on a pan in a 350 oven for 6-7 minutes, but watch carefully, as they burn quickly.
