I need a salad to go with chicken chilli

A copped caesar salad would go well.

When I serve chili or my husband makes fajitas, I make a green salad (with butter, Boston or Romaine lettuce), mix some cilantro leaves in with the greens, add cubed salted avocado and use this dressing: https://food52.com/recipes/34188-smoky-honey-lime-vinaigrette

Make a sweet corn, black bean, avacado salsa/salad.

Kale, toasted bread crumbs, Parmesan shavings, dressed with a punchy lemon vinaigrette with help liven up the heaviness of a chili.

Make a basic or favorite coleslaw
Add some apple or pear for a seasonal note, and one of dried cranberries or fresh pomegranate seeds for a bit of color.
