In a bowl combine the romaine, corn, and cherry tomatoes.
Add 3/4 cup of avocado. Place the remaining avocado in a blender along with 1/3 cup water, lime juice, and chili powder; season with salt and pepper.
Pour dressing over the salad; toss gently.
The dressing is reeeeally bland. I added cilantro, cumin, salt, and pepper. It helped a bit. I may try again using plain yogurt instead of water.
I agree that cilantro would totally brighten up the flavors a little, but regardless, this dish was great for an end of summer starter. I have never made anything with raw corn before -- it had a crisp and starch-like texture that everyone around the table enjoyed. Will absolutely make again.
A bit of chopped fresh cilantro might make a nice addition to this salad ~
