These are pretty easy to make. First I take a rolling pin and flatten out a piece of bread.
I roll it until the bread looks like this. If you want to cut off the crusts, this would be the point to do it.
Next, I add a couple of decently-sized pieces of salad greens. I use whatever I have on hand. Spinach is a favorite of my older son. You can probably add more, but my sons usually eat more than the 4 you get out of one piece of bread. You could also add cucumbers or carrot sticks. I just didn't have any on-hand.
Then I add one piece of turkey, or whatever deli meat or cheese I might have.
Then I roll it up very tightly starting at the end with the veggies and meat.
I cut it in quarters and serve it. I usually make 3-4 of these. Squirty will eat at least 8 pieces depending on what else he has for lunch.
