Feed the orphans - Orphanage support

My recent visit to two Orphanages in Sylhet left me tearful and desperately searching for ways to help them. I took a look around their kitchen and the lunch for that day overwhelmed me with emotions. They had one curry of no more than 15 eggs and sliced potatoes to share amongst almost 30 children with a pot of rice. I knew before I went these were societies most vulnerable but I expected there to be more. Like one big curry rather then a barely enough one. They literally wouldn't be full, ever, and I found this reality really hard to take in. These children have so little and literally sleep, study and eat in one room. We are in a privileged position that can provide more for them. The very next day we raised enough to feed them and we personally cooked this and they made the longest dua for us. I want us to be able to more meals for them, especially during Ramadan, to feed them special like we have in Ramadan what can be more rewarding for us?
