Why it works: Catfish and onion work together. They rank in the top 6% of all ingredient pairs, and 175 recipes mention both. Both carry 2-methylbutyraldehyde, which smells malty, chocolate. The science ↓
The recipe
Ingredients
Contains: fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the dressing
Combine the balsamic vinegar, olive oil, water, Dijon mustard, salt, black pepper, and minced garlic in a jar with a tight-fitting lid, then screw the lid on tightly and shake to blend.
Preheat the grill to medium-high heat.
Marinate
Place the catfish fillets in a quart-sized resealable bag and pour one-quarter of the dressing over them.
Shake the bag vigorously and refrigerate for at least 15 minutes.
Divide the vegetables (except lettuce) into two gallon-sized resealable bags and pour one-quarter of the dressing into each bag.
Shake each bag vigorously and refrigerate for at least 15 minutes.
Grill and serve
Oil the grill grates.
Grill the catfish fillets and vegetables, turning once, until the fillets are opaque and flake with a fork and the vegetables are cooked to desired tenderness.
Let the grilled items cool for at least 5 minutes.
Dice the grilled vegetables and fillets into bite-sized pieces and add to lettuce, then top with the remaining quarter of dressing and the reserved dressing from the vegetable bags.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Catfish fillets
- Main protein that turns opaque and flaky when cooked through.
- Balsamic vinegar
- Provides the sharp acidity that gives the dressing its tangy flavor.
- Olive oil
- Fat that carries the garlic and mustard flavors and coats the fish and vegetables.
- Dijon mustard
- Helps emulsify the oil and vinegar so the dressing stays blended and clings to food.
- Garlic
- Adds pungent aroma to the marinade and dressing.
- Eggplant
- Absorbs the marinade and becomes soft and tender on the grill.
The step that matters
Grilling the catfish until just opaque and flaky. Catfish fillets are thin and lean, so they cook quickly. Overcooking squeezes out moisture and makes the flesh dry and tough, while undercooked fish stays translucent and loose. Turning once helps it cook evenly.
Flavor stand-ins for the asparagus
How well each one fits the dish's main ingredients (catfish, garlic, onion, pepper, eggplant, corn, lettuce):
- Capsicumbetter flavor fit
- Tomatobetter flavor fit
- Okrabetter flavor fit
- Asparagusthe original
Fit is the average pairing score against catfish, garlic, onion, pepper, eggplant, corn, lettuce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
