Repashy grub pie feeding amounts

Marlow is 9months old and I’ve had him about 3weeks now.
He is ok at eating vege ( mainly squash , rocket and red capsicum as staples and we change around what we put with it each day out of green beans , carrot , apple , grape , peas ) and we do a small sprinkle amount of bearded dragon pellets on top daily.
Live food is very expensive here - like $1 a bug type expensive- so we can’t get them daily , just once every so often. But I do feed flukers tinned bugs daily but that’s getting pricey too at $20 a can so I really need to stretch a can over 4 days to get the cost of bugs down to $40 per week instead of $20 ish a day
So I brought repashy grub pie and he loves it! A big container of repashy is $62 here but it’ll last ages

I have no idea how much to feed him though of it and can I do it everyday as a staple?
I was thinking still do all his veges , and 6-8 canned bugs (grasshoppers or crickets ) daily and then repashy grub pie
How much grub pie should I do? Like a ice cube size ? Or double?
I gave him a ice cube size today , obviously broken into like 8 pieces though , and he loved it!

Should instructions on the bottle.

This is good guide too :

The packet says nothing about amount , just how to prepare and then store it
From your chart and past threads it seems about a tablespoon is right for his age group - I think I’ll do that much in the morning then he can eat his vege with pellets throughout the day and then at 4pm I’ll do some canned crickets or grasshoppers

Thanks
