Quoted By:
Unfortunately you had a few grammatical mistakes within your post. I am here to fix them for you:
Corrections:
"ated" should be "ate" (past tense of "eat").
"recces" should be "Reese's" (proper noun and brand name).
Punctuation: A period is added at the end to complete the sentence.
So the correct sentence would be "Just ate a bag of Reese's Puffs."
You're welcome! :D
