Sweet and Sour Pork

This is my aunt Vivian's recipe:

Carrots
Green Pepper
Celery
Onions
Pork
1 tbsp Cornstarch
1 tbsp flour
1 egg
1 can pineapple chunks

Put rice on to cook. Saute in butter: carrots, green pepper, celery, onions, until they are basically done. Dip pieces of pork in cornstarch, flour, and egg, and fry.

Sauce:
1/3 cup wine vinegar
1/4 to 1/2 cup sugar
1/2 cup water
1 tbsp cornstarch
1/2 cup ketchup
Tomato sauce to taste

Place veggies on rice. Place chunks of pineapple and pork on veggies. Cover with sauce.
