Hi mhynne im not really good cooking pinakbet but i have my own version
for pinakbet i just use squash or kalabasa from asian store, okra, aubergine, ampalaya from my local town market or asda or asian shops, green beans etc.
sometimes if i dont have ampalaya i still cook pinakbet..
for sahog - sometimes i use pork, dried fish or squid etc.
for seasoning-fish sauce and anchovy sauce or sauteed shrimpsoning mix or knorr veg cube, sea etc.
for tinola- same above, i just buy the sayote in the asian shop the rest like chicken green beans, ginger etc you can find them anywhere, then add fish sauce and some seasoning
I'd love to grow lemon as well, is't easy though?
