[Request/Discussion] Taste difference Lettuce vs Spinach? https://ift.tt/eA8V8J

I eat Subway daily and have contemplated substituting spinach for lettuce due to all of the health benefits. I haven't eaten spinach since I tried it as a child from a can after watching Popeye. It was disgusting. This would be raw spinach leaves at Subway though and it looks similar to lettuce. Just dont want to ruin my sub if it taste awful so hoping to get a good piece of feedback on taste between the two. Yes, this probably seems like a dumb post but totally legit. Thank you in advance.
