Heat olive oil in a 10-inch skillet. Cook onion over medium heat until tender.
Add garlic, zucchini, parsley, and basil. Cook until zucchini is tender-crisp, about 5-6 minutes.
Add tomato, seasoned salt & pepper. Cook an additional 2-3 minutes.
Remove from heat, sprinkle with cheeses and cover with a lid, rest 2-3 minutes, or until cheese melts.
