Lemon Chicken

I think my mom got this recipe off the side of a Minute Rice box.

2 boneless chicken breasts
1 small onion (optional) - I use dried onion
2 T. butter/margarine
1 can of chicken broth (or granules)
1 T. corn starch
1 large carrot (sliced)
2 T. lemon juice
1 t. lemon rind (grated)
1/2 t. salt
1 small bag peas (frozen)
1 1/2 c. Minute Rice

Brown chicken, onion and butter together.  add cornstarch and cook another minute.  Add broth, carrots, lemon and salt.  Bring to boil. Add peas and rice. Remove from heat, and let stand 5 minutes.
