Why it works: Basil and tomato match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 3,979 recipes mention both. Both carry 3-hexenal, which smells apple, fruity. The science ↓
The recipe
Serves 6Ingredients
Contains: wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: pasta
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Bring a large pot of salted water to a boil. Add the rotini and cook until just tender, about 7 minutes. Drain and rinse under cold water.
While the pasta cooks, trim the green bean ends if using fresh. Add the beans to the boiling water for the last 2 to 3 minutes until crisp-tender, or use canned beans drained. Drain and cool.
Place the cooled pasta and green beans in a large bowl.
Add the sliced red onion, diced tomato, chopped basil, and drained tuna to the bowl. Gently break up the tuna with a fork.
Pour the Italian dressing over the salad and toss well to coat.
Cover and refrigerate for at least 30 minutes so the flavors blend. Toss again before serving cold.
