2 Leftover Chicken Breasts. What Do You Make With Them?

I'd probably do stir fry chicken, slice them up and add lots of whatever veggies you like, with some teriyaki sauce, or something similar.  We get cauliflower rice from Trader Joes to serve with it.  

I'd put it on a salad.

Pulled barbecue chicken on loaded baked potatoes with a side of salad or slaw.

Quesadillas
Burritos
Tostadas
Stir fry
Chicken salad sandwiches
Chicken rice or chicken tortilla soup

I'd slice them up and use them to take to work for lunch.

Id make a homemade chicken pot pie.

Tortilla soup. Not the heavy stew kind with beans and corn, but the light, chicken broth based one with carrots, celery, tomatoes, cilantro, lime juice. Not a calorie in a carload. Top with thin crispy tortilla strips.

1 pound boneless skinless chicken breasts, cut into strips
1 can (10-3/4 ounces) condensed cream of chicken soup
1 cup frozen peas

This is usually what we do! :-)

Cut them up and put them on top of a Caesar salad.

I make a veggie pasta dish with sautéed veggies (mushroom, zucchini, onion, bell pepper, yellow squash, etc.) and a light cream sauce with 1/2 a cup of white wine and 4 oz cream cheese. I've used leftover chopped chicken in it before, so that's probably what I'd do.

I was recently in the same predicament so I used them to make chicken alfredo over penne noodles. YUM!
