These pinwheels are absolutely delicious... don't wait for a party to make them, whip them up for a weekend brunch or evening snack! You can make these up to 1 day ahead and refrigerate. You should get around 48-50 pinwheels/sandwiches if you slice each bread roll into 8 pieces, but it will depend on how large you slice them, so servings is only estimated. Don't purchase the completely square slices of bread, purchase the sandwich loaf that is higher on the top. Plan ahead these need to chill for a minimum of 2 hours before slicing. You can also make these with fresh steamed asparagus, but I prefer the canned better.
