I used hot dog buns instead of slider buns. I trimmed off the rounded edges of the hot dog buns and cut them into 3 pieces. This gave me the perfect bite sized slider bun.
I used the trimmed edges to make bread crumbs. Just stick the trimmings into a food processor and pulse until you get small crumbs. Spread the bread crumbs onto a cookie sheet and cook in a 200 degree Fahrenheit oven for about 18 to 20 minutes. Stir the crumbs about halfway through the cooking.
