Heat olive oil in a large skillet over medium-high heat.
Add the sliced onion and sauté for 2-3 minutes until they become translucent.
Stir in the minced garlic and cook for an additional 30 seconds, ensuring it doesn’t burn.
Add the bell peppers and zucchini to the skillet, cooking for about 4-5 minutes until they begin to soften.
Toss in the broccoli florets and continue to sauté for another 3-4 minutes until all vegetables are tender yet crisp.
Incorporate the cherry tomatoes and balsamic vinegar, stirring gently to combine. Cook for an additional 2 minutes until tomatoes are slightly softened.
Season with salt, pepper, and dried oregano, stirring to ensure even flavor distribution.
Remove from heat and garnish with freshly chopped basil before serving.
Notes
Serve warm on a colorful platter, and sprinkle extra fresh basil on top for vibrant color contrast. You can also add a sprinkle of feta cheese for an additional flavor boost.
