Swing by the freezer section for one of our favorite convenience items—frozen sweet potatoes. If you want to skip the meringue in Step 2, top with miniature marshmallows instead.
Preheat oven to 400°. Steam potatoes according to package directions. Mash together sweet potatoes and next 5 ingredients. Spoon mixture into 8 (6-oz.) custard cups. Place on a baking sheet.
Beat egg whites at high speed with an electric mixer until foamy. Add sugar, 1 Tbsp. at a time, beating until stiff peaks form and sugar is dissolved. Spread meringue over sweet potato mixture.
Bake at 400° for 10 minutes or until golden brown.
Note: We tested with Ore-Ida Steam n' Mash Cut Sweet Potatoes.
