CF,
Welcome to the forums. Have you tried fruits and veggies with your veiled before? To answer your question, you can dust your F&V's if nothing else is being offered that day. I don't due to my dusting schedule with my feeder insects that are being offered. Ideally, you should offer all items in the am, so that your guy/gal has time to properly digest them by nightfall. Fruits in small quantities can be very beneficial to your veiled if he/she will try them. I feed bits of strawberry when in season, but usually just gutload my feeders with what will be beneficial to Lucky (my veiled). Here's a link that will give you some guidelines on what to try.

Suggested Ingredients
Best - These gutloading ingredients are best because they are highest in calcium, low in phosphorus, oxalates and goitrogens. They should be the primary components of your gutload: mustard greens, turnip greens, dandelion leaves, collard greens, escarole lettuce, papaya, watercress and alfalfa.
Good - These gutloading ingredients are good because they are moderately high in calcium and other vitamins/minerals. They should be used in addition to those from the previous category: sweet potato, carrots, oranges, mango, butternut squash, kale, apples, beet greens, blackberries, bok choy and green beans.
Avoid These Ingredients
