The current Penzey's Spices catalog has a salad recipe you might be interested in, Mame. It sounds similar to your corn salad except that it has pasta and avocados and tomatoes instead of corn, zucchini, and peppers. I plan to make it myself as soon as I have some avocados. I'm adding your corn salad to the list too.

Avocado Pasta Salad
This pasta salad is great when avocados are at their peak-ripe, flavorful and inexpensive. While the salad can be made ahead of time and refrigerated for a few hours before serving, add the avocados at the last minute before serving for the best color and flavor. Pasta salad is always great for a healthy, tasty summer meal.
1 lb. bag dry pasta (we like tricolor rotini, fusilli, or wagon wheels for parties)
1/2 Cup crumbled feta cheese (shredded Parmesan is also very tasty if you aren't fond of feta)
1/2-1 pint cherry tomatoes, cut in quarters
1 bunch green onions, ends removed, thinly sliced
1-2 ripe avocados, peeled and chopped
Dressing:
2-3 TB. COUNTRY FRENCH VINAIGRETTE
2-3 TB. water
3-4 TB. balsamic or red wine vinegar
1/2 Cup light mayonnaise
1/4 Cup olive oil
1 TB. honey
Boil the pasta according to the package directions. While it is cooking, clean and chop the vegetables and crumble the cheese. In a large serving bowl, mix the COUNTRY FRENCH VINAIGRETTE with water; let stand a few minutes, then whisk in the rest of the dressing ingredients. Rinse the pasta and drain very well. Toss the pasta with the dressing. Add the onions, tomatoes, avocado and cheese, then toss again and serve.
Prep. time: 10 minutes

Here's a description of the Country French Vinaigrette seasoning mix so you can make the blend on your own:
Country French Vinaigrette
Similar to the house dressing of many fine restaurants, filled with flavorful French herbs, not too tart, lightly thickened by crushed brown mustard. A variation of classic French Vinegar and Oil dressing, but lighter, perfect for today's salads. Bursting with flavor, blend with a mix of olive oil and red wine vinegar (the proportions can be varied to suit your tastes). Basic recipe for 1 cup dressing: Mix 1-2 TB. seasoning in 2 TB. water, let stand 5 minutes. Whisk in 1/3 Cup red wine vinegar and ½ Cup olive oil, refrigerate. Hand-mixed from: sugar, brown mustard, salt, garlic, black pepper, lemon, onion, French tarragon, white pepper, chives, thyme, cracked rosemary.
