Step 1) Place bread cubes, tomatoes, cucumber, onion and romaine in large serving bowl.
Step 2) Combine sugar, basil, sea salt, garlic, black pepper and red wine vinegar in a mixing bowl. Let sit 5 minutes for flavors to develop. Whisk in corn oil gradually.
Step 3) Toss salad ingredients with 1/4 to 1/3 cup salad dressing until thoroughly combined. Served immediately. Refrigerate remaining salad dressing in a sealed container for up to one week.
Recipe Tip: For crisper bread cubes, toast in a 350°F for 3 to 5 minutes.
