what's for dinner?

[cannongal]

Frozen 3 color cheese tortellini
feta cheese chunks
cheddar cheese , cut into bite sized chunks
Salami,  if you get t at the deli, ask them to cut it into quarter inch slices, the chunk it.
cherry tomatoes, halved
English cucumber,  halved the cut into chunks
I black olives 
Greek dressing, bottled. 
Fyi, cook the pasta until just done, otherwise they fall apart.

I have a question, is the Greek dressing necessary or can it be a personal preference? I have Olive Garden house Italian and I'm wondering if I can use that in place of the Greek dressing. It should be fine, right? I'm not someone who should experiment in the kitchen.

Any type of vinaigrette is fine.  Greek is a personal preference for me.
