Some ideas i made 
(Plants)
1.Eggplants
Wild eggplant bushes can be found in greenlands, can produce 2 eggplants.
To get seeds you need to pick up the 2 eggplants first and then use a sharp stone to cut the bush for a seed
Once planted it and watered wait 2 minutes and it can produce 3 eggplants! After picked all the eggplants you need to water it and it can produce it again.
2.Lettuce
Lettuce can be found in swamps, use a sharp stone to collect 1 piece of lettuce leaf do this 2 times and you will be left with a lettuce seed
Plant the lettuce and water it wait for 2 minutes and it will make 3 lettuce leafs each lettuce plant! Use sharp stone to get the leafs (only wild ones give seeds)
3.Bamboo
Can be found in jungles pretty common use sharp stone to cut a bamboo patch cannot be planted
(Food types)
1.Eggplant salad
Need eggplant with lettuce leaf, put the eggplant in a bowl and the lettuce.
After that use a sharp stone to crush it and you have a salad! It will give 6+ hunger points
(Building)
1.Bamboo flooring
Will need one bamboo patch and place it on flooring stakes
2.Straw flooring
Get wheat straw with no wheat and place it on flooring stakes
