How to get organic audience for a facebook page?

I am working in a startup, and we are going to launch an app related to food industry. It's going to take another 3-3.5 months to make it live. My boss has given me the task to build audience on facebook page and I have no idea how to do it. I created a page and I am posting some meme's. Any tip's/guidance on what kind of content to post? I dunno to cook , and posting recipes is out of question We have planned for atleast 50,000 likes before going live. And I don't want any fake likes. How to get genuine likes?

Thanks

The best way to increase the reach and real likes is by posting viral content.

Write articles related to the niche of your app and post then on your facebook... Post your page's add on the pages/groups of same niche...

Food app => Make 60 seconds recipe videos.
Go to youtube and instagram, search for recipe videos, download and reupload to your FB page.

I think this would be the best advice which you will find here. Combine this advice with joining in related facebook groups.
