I often put leaves from bolted lettuce into my fruit-veggie smoothie. The smoothie tastes great. I wonder if I could also put the actual STALKS of bolted lettuce into the smoothie? I’ve searched on Web “are bolted lettuce stalks edible” , “are bolted lettuce stalks nutritious”, etc. but get nothing (except info about the Chinese stalk-lettuce). And some bolted stalks have seeds at the top. Are the seeds edible? Nutritious? Again, web search has yielded no info.
