So you have a boneless skinless chicken breast, already grilled
Only seasoned with salt & pepper. It's been in the fridge for a couple days, so it's cold.
What would you do with it?
Edit to add: That's not just throwing it on top of a salad.
1) Dice, add ff mayo, mustard and my BIL's homemade relish to make chicken salad filling for sandwich.
2) Dice and make cheater pot pie in an 8x8 dish, adding cream of potato soup, frozen mixed veg and some sage for the filling, topping with a half-roll of crescent roll dough (make rolls with the other half), or use puff pastry to top.
3) Make chicken gyro, using pita or Naan bread, and homemade cucumber/yogurt sauce.
Having had one of those just two days ago, I sliced it up and combined it with other leftovers. Happily, my other leftovers included cooked rice and frozen peas and corn. I spiced up my fried rice with some garam masala and at the very end added the juice of a half lime that was also destined for the trash if I didn't use it. It was delicious.
Slice and saute with garlic, olives, capers, halved cherry tomatoes. Toss with hot pasta, some cheese, and butter. Grind of pepper; maybe a squeeze of lemon.
Quick soup: Cook quinoa in a 4x volume of chicken stock with chopped onion. Add finely diced chicken and handful of frozen peas. Heat through. Garnish with lemon zest.
Sandwich! Hard roll, fresh mozz, roasted pepper, basil, balsamic vinegar. Can sub grilled sourdough, sundried tomato and pesto instead.
Panini! Swiss cheese, ham, arugula, flavored mustard or cranberry chutney.
Dice or shred. Toss it with jerk, thai peanut or spicy bbq sauce and use it as a pizza topping with appropriate veg and herb.
