In a large saucepan, bring 1 in. of water to a boil; place the corn and peppers in a steamer basket over water. Sprinkle with seasonings. Cover and steam for 8-10 minutes or until vegetables are crisp-tender.
Transfer vegetable mixture to a serving bowl. Add tomato and parsley; toss gently.
Wear disposable gloves when cutting hot peppers; the oils can burn skin. Avoid touching your face.
