Rainbow plant life also has some good recipes for vegan cheese/creamy sauces. This is a nut free and tofu free one https://rainbowplantlife.com/nut-free-vegan-cheese-sauce/#recipe. The one I like is a cashew queso but I appreciate that cashews can be expensive.
If you can tolerate nutritional yeast it helps give things that cheese umami flavour. Might be some ideas here anyway
Ah sorry 😞 hope the tofu experiment works out.
