Wash and prepare all vegetables.
In a large serving bowl, arrange the cherry tomatoes, cucumber, bell pepper, snap peas, corn, red onion, goat cheese, and sunflower seeds.
In a small bowl or jar with a lid, combine olive oil, red wine vinegar, minced garlic, salt, black pepper, and red pepper flakes if using.
Whisk or shake until the dressing is fully combined.
Just before serving, pour the dressing over the vegetables.
Toss gently until everything is evenly coated. The goat cheese will soften and create a creamy coating throughout the Summer Vegetable Salad.
Sprinkle with fresh parsley or basil and serve immediately.
