Hmmm I'd limit myself to the dollar store I guess

Pick up 2 small bags of rice - $2 a pack of salt and pepper $1 Three cans of tomato paste $1 lemon juice - $1 1 bag of pasta - $1 1 container of oil - $1 3 spices - Oregano. paprika and chili powder $2 bag of dehydrated vegitables (technically for soup) $1

Sounds pretty meager but you can live off it. Gotta stick to what feeds you.

for something more interesting this is where my skillset would come in handy ;)

Then i'd walk to the woods

Gather morels and other delicious fungi

Find a field

gather clover, wild mint, dandelion, nettle, sumac (not poison sumac the edible kind), wild blue berries or other wild fruits.

Goto the traintracks and gather raspberries. They grow along them here.

Find a pond

grab a few lilly tubers and cattails

Goto the river and fish.

Now I have the ingredients to eat like a king ;)
