In a small bowl, add mayonnaise, olive oil, Dijon mustard, red wine vinegar, salt, pepper and hot sauce. Whisk the dressing and set aside.
In a large bowl, add chickpeas, tuna, pickles, red onion and dill.
Pour salad dressing on top and stir gently with a spoon to combine.
Let salad chill in the fridge for about an hour before serving. Serve cold.
Notes
Store: Refrigerate tightly covered for up to 3 days. You can always rehydrate the salad with some olive oil.
Freeze: I think you can freeze leftovers since there are no veggies in the salad but I haven't tried. Freeze in an airtight container for up to 3 months and thaw in the fridge overnight.
