。
I enjoyed the meal mother made for me.
Literal
Mother [subject-が] made-for-me meal [obj-を] tastily ate.
おいしく食べる ('eat deliciously') uses the adverbial form of おいしい to describe the manner of eating — 'ate with enjoyment,' 'ate with relish.' Japanese attaches adjective-adverbs directly to verbs for this kind of manner gloss, where English would need a phrase like 'with relish.' 作ってくれた forms a relative clause modifying 食事.
