I actually consume a veg burger, however it look like a meat burger. I did investigate and find out that it was veg burger. However, my inner voice keep telling me that i have done something wrong. I had an option to stop myself but I did ate it.
In the name of Allah, Most Gracious, Most Merciful
Assalaamu `alaykum waRahmatullahi Wabarakatoh
If you ate a vegetable burger, that is permissible on condition there was no contamination in anyway with haram meat. If you have a doubt, you should abstain from eating out.
