Making a quick and simple fresh pesto, but no pine nuts and no time to market. Any good subs?

My son has a severe nut allergy, so I've never used any nuts in my pesto, just basil, good olive oil and some garlic.

Walnuts are even better!

walnuts, pecans, or almonds (skinned).

I also like using hazelnuts, but you can really use any kind of nut in your freezer. I've also used toasted pepitas and it came out well.

This is probably too late but my dad is famous for his pesto and he always uses walnuts. Basically he's too cheap to buy the amount of pine nuts he'd need for the quantities of pesto he makes (my mom grows A LOT of basil) and I've frankly never noticed a difference.

Agree with keel, walnuts are what I use in a pinch.

Almonds make for a crunchier pesto, which can be nice.

Walnuts are a good sub or you could try pepitas.
