Most of the menus on allearsnet.com show appetizers/starters as soup, salad, chips/dip, shrimp cocktail, etc. As long as you're not choosing an appetizer/starter that's for more than 1 person (such as a sampler), you should be able to get it - you'll probably see most appetizers costing about $5-8. CMs are known to help you maximum the plan (and benefit themselves with larger tips based on the total bill!), so it doesn't hurt to ask when in doubt.
Hope this helps.
