There are just some things that shouldn't be mixed, and today it's obvious that vegetables and jello is one of them. Someone posted a jello salad full of tomatoes, carrots, peas, corn and green beans to Reddit, and it honestly just looks like a glob of half-digested veggies. Just think about what the texture must be like -- can you do it without shuddering? The lettuce garnish doesn't exactly make it look more appetizing, but good try.
In the future, let's please all just agree to stick to fruit and pretzels in our jello salads. Not veggies.
