Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peppers
- Provides the main crisp, fresh vegetable body and mild bitter flavor of the salad.
- Tomatoes
- Adds juiciness and acidity, brightening the flavor of the salad.
- Onions
- Contributes sharp aroma and pungent flavor that balances the sweetness of the vegetables.
- Romaine lettuce
- Forms the crisp base that holds the rings and adds fresh, watery crunch.
- French dressing
- Adds fat, acidity and sweetness that moisten and season the vegetables.
The step that matters
Chill all ingredients on ice.. Cold keeps the lettuce and peppers crisp, since chilled cell walls stay firm and resist wilting. Keeping everything cold until serving preserves the fresh texture of the salad.
