It wasn't this old nugget of a recipe was it?
I've had this for 40+ years. Don't know if this is what you are looking for- you could put the liquid in hot or room temp- doesn't matter. It is pretty tasty even if it is canned veggies.
QUICK VEGETABLE SALAD (serves 6-smileys/bigeyes.gif
1 can (15 oz) french cut green beans with 1/2 of the canned liquid
1 can (15 oz) small kernel white corn with 1/2 of the canned liquid
1 can (15 oz) small peas, drained
1 chopped medium onion
1 chopped green pepper
1 C chopped celery
1/2 C cliced or chopped green stuffed olives
3/4 C vinegar
1/2 c vegetable or olive oil
1/4 C sugar
1 tsp pepper
1/2 tsp salt
Mix beans with their liquid, corn with its liquid, peas, onion, green pepper, celery and olives in a large bowl. Whisk vinegar, sugar, pepper and salt together and drizzle oil while whisking to make dressing. Pour over veggies and mix. Refrigerate.
