If using frozen corn and edamame, put it all in a bowl large enough to hold the finished salad but small enough to fit in the microwave, if possible. Don’t need to cook the corn, just take the chill off of it. Or, just let it sit out and defrost or leave it in the fridge to defrost.
Make the dressing by squeezing the lime juice into a bowl, add the chopped garlic, salt and pepper, then whisk in the olive oil. Set this aside and let the flavors blend.
Now prep the rest of your vegetables – cut your cherry tomatoes in half, slice the green onions finely, chop your cilantro, cut the avocado into largish bite size pieces so it doesn’t mush in the salad and if using jalapeno or hearts of palm, dice and slice as well.
Add the tomatoes, green onions, and cilantro (jalapeno and hearts of palm if using) to the corn and edamame mixture and combine gently, then add the avocado and dressing and combine well but gingerly so as not to mush the avocado. Now just cover and either place in the fridge or even leave it on the counter for a few hours if fridge space is spare.
