Hi Tessie,
Have you considered Damper: I have a recipe for Plain Camp Fire Damper.
900g (6 cups) plain flour
1 tablespoon baking powder
pinch salt
500ml (2 cups) milk, warmed
Combine flour, baking powder and a pinch of salt. Gradually add milk, stirring until you have a soft dough.
2 Place the camp oven over hot coals and heat until hot. Carefully place dough in oven, cover with a lid, surround with hot coals and bake for 30 minutes or until cooked through.

You could perhaps try with almond, soy or rice milk and see if it works in the oven.
Best of luck

I do the same but my friend can’t use some ingredients. Thanks for your reply

Not sure how good your bread will be using just ordinary old plain flour. I use the flour that goes with the bread machines, perfect bread every time
