Grilled Vegetable Salad with Kesong Puti

I'm thinking of preparing this salad later for a friend's birthday dinner using kesong puti instead of feta.  Hope they'll like it.  Some of the grilled vegetables can also be tossed in pasta and we'll have another dish.  Might taste the same but I guess the difference will be that the salad will be tangy because of the vinegar and the pasta will be savory.  I wonder if I can get caramelized walnuts later at the groceries to add to the salad.  Maybe instead of caramelized walnuts, I can use honeyed cashews or pili nuts.  

Wish me luck.
