This is a "Southern Living" recipe that I've made for years and years:

Strawberry-Romaine Salad
(12 Servings)

1 cup vegetable oil
3/4 cup sugar
1/2 cup red wine vinegar
2 cloves garlic, minced
1/2 tsp salt
1/2 tsp paprika
1/4 tsp ground white pepper
1 large head Romaine lettuce
1 head Boston lettuce
1 pint strawberries, sliced
1 cup (4 ounces) shredded Monterey Jack cheese
1/2 cup chopped walnuts, toasted

Combine first 7 ingredients in a large screw-top jar. Cover tightly, and shake vigorously. (NOTE: This can be made up to one week ahead of time. Store in refrigerator.)

Tear lettuce into bite-size pieces. Combine torn lettuce, strawberries, cheese, and walnuts in a large salad bowl. Shake dressing vigorously; pour over salad, and toss gently.
