Rinse all the vegetables and fruits under cool water. Pat them very dry with paper towels so the tray stays crisp. Wet produce slides around and makes the dip watery, so this step matters.
Slice the cucumbers into thin rounds and cut the celery into small chunks. Halve the cherry tomatoes if you like, and cut the broccoli into small florets. Keep the baby carrots whole, since they need no prep at all.
Peel and segment the oranges, then slice the apples and toss them with lemon juice. Wash the grapes and strawberries and pat them dry. Hold the banana back, because it browns fast and should be sliced last.
Spread the baby carrots across the center of your tray until the whole round shape looks orange. Don't worry if some carrots sit a little crooked. A slightly messy pumpkin still looks wonderfully spooky.
Place the celery chunks at the top for the stem. Set the mini bell pepper in the middle as the nose. Arrange the cucumber rounds below it in a wide, grinning jack-o'-lantern smile.
Spoon the hummus into two small bowls and place them above the nose as glowing eyes. Add the ranch dip in a third bowl at the side for variety. For a spider veggie tray twist, top one bowl with olive slices shaped like a spider.
Thread orange segments, green grapes, and purple grapes onto skewers for bright Halloween colors. Slice the banana and tuck it with the apples around the tray edge. Finish with strawberries so their tips look like silly monster tongues.
Tuck the broccoli, snap peas, and tomatoes into the open spaces. Check the tray from a few steps back and fill any bare spots. Serve right away or chill it until the party starts
