I had a wonderful version of this at a party in Boston years ago. Been looking for the recipe ever since. This one adapted from from Divas Can Cook comes close.
SALAD
1 c frozen corn sweet corn
1 can black beans, drained
dice the following to a similar size as the corn
2 bell peppers, diced – choose two different colors for visual appeal

1 pint grape tomatoes, diced
2-3 cloves garlic, minced

CHILI LIME DRESSING

Place salad ingredients in a large bowl. Wisk dressing ingredients together in a small bowl.
Pour dressing over salad and toss to combine. Refrigerate for at least an hour; it gets better as the flavors meld. Add avocado if desired, toss gently before serving.
