Pick a large serving or salad bowl and place the properly drained and rinsed red kidney beans in it.
Add in the fresh or frozen sweet corn kernels, finely diced onion, halved cherry tomatoes, lime juice and the lemon zest.
Use both of your hand to hold the bowl firmly and gently toss the ingredients until mix up properly.
Set the bowl on your kitchen table or kitchen countertop and drizzle the bean mixture with some olive oil.
Now, season the salad with some salt and freshly ground black pepper to taste.
Gently mix the ingredients with a large fork.
Add in the finely chopped fresh basil and serve.
Note: If you do not serve the salad immediately and want to chill it for some time, then make sure to add in the basil few seconds ahead of dishing it up.
