How to modify this CFG to use the conjunction (and) for two sentences? SWI-PROLOG

I wrote the following CFG to parse sentences such as (tom ate pizza), (bill ate rice)...etc.in PROLOG.

s(s(NP,VP))-->np(NP),vp(VP).

vp(vp(VBD,NP))-->vbd(VBD),np(NP).
np(np(NN))-->nn(NN).
np(np(NNP))-->nnp(NNP).

nn(nn(pizza))-->[pizza].
nn(nn(rice))-->[rice].
nnp(nnp(john))-->[john].
nnp(nnp(harry))-->[tom].
vbd(vbd(ate))-->[ate].

I would like to modify the grammar so that it can parse the same sentences joined with (and). I need to parse (tom ate pizza, and bill ate rice).
