i like it!
butt heres some things you may want to consider
if your doing the common app online, im not too sure if you can use the hypens or dashes w.e. its called. and if so, you MUST finish it off. you didnt here.
however- they are low in sugar, and thus a healthy option with
this should be: however-they are low in sugar-they are a healthy option...
(because once you close off the dash you have to make sure the however and the other part makes a complete sentence)
obviously this is a little awkward so i think you should consider rewriiting this sentence.
and then im sure you know that your second paragraph is a little shaky, but its still very good. i rly like what you do :) VERY unique.
Selling these healthy cookies in order to promote healthy eating choices is just one activity we did.
^^ the 2nd paragraph ws great, but you should end it with someting better than this
good luck! :D
