[SalesForce] Trigger to insert Child Object Records based on various relationships

I am create a custom object record on Opportunities called Recipe Sheets (based on the Opportunity Line Items) and this trigger is working properly. Then I have a second trigger firing on the insert of these Recipe Sheets to create Recipe Sheet Items based on the Product Items associated to the Products in the Opportunity Line Items.

If I deactivate Trigger 2, Trigger 1 works, but when I activate Trigger 2 I get this error:

"Error:Apex trigger NewRecipeSheets caused an unexpected exception, contact your administrator: NewRecipeSheets: execution of AfterUpdate caused by: System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, CreateRecipeItems: execution of AfterInsert caused by: System.DmlException: Insert failed. First exception on row 0 with id a07Z000000HdDsxIAF; first error: INVALID_FIELD_FOR_INSERT_UPDATE, cannot specify Id in an insert call: [Id] Trigger.CreateRecipeItems: line 22, column 1: []: Trigger.NewRecipeSheets: line 24, column 1"

Does anyone have any suggestions for what I am doing wrong in Trigger 2?

Trigger 1

trigger NewRecipeSheets on Opportunity (after update){

    List<Recipe_Sheet__c> RecipeList =new List<Recipe_Sheet__c>();
    List<Opportunitylineitem> opplinitemlist =new List<Opportunitylineitem>();
    List<Opportunity> Opportunitylist =new List<Opportunity>();

    for(Opportunity opp :trigger.new){
        if(opp.Stagename=='Closed Won'&&opp.Create_Recipe_Sheet_s__c==True){       
        Opplinitemlist =[select Id,PricebookEntry.Product2.Name,PricebookEntry.Product2.Do_Not_Discount__c,PricebookEntry.Product2.Record_Type_ID__c,Total_Drop__c,Finish_s__c,Notes__c, For_Vaulted_Ceiling__c,PricebookEntry.Product2.id from Opportunitylineitem where Opportunityid =: opp.id AND Product2.Do_Not_Discount__c=False];
        Opportunitylist  =[Select Accountid from Opportunity where Id =: opp.id];

        for(Opportunitylineitem Opplist :opplinitemlist ){
        Recipe_Sheet__c rec =new Recipe_Sheet__c();
        rec.Opportunity__c =Opportunitylist[0].Id;
        rec.product__c=opplist.PricebookEntry.Product2.Id;
        rec.Name=opplist.PricebookEntry.Product2.Name;
        rec.For_Vaulted_Ceiling__c=opplist.For_Vaulted_Ceiling__c;
        rec.Finish_s__c=opplist.Finish_s__c;
        rec.Notes__c=opplist.Notes__c;
        rec.Total_Drop__c=opplist.Total_Drop__c;
        rec.RecordTypeID=opplist.PricebookEntry.Product2.Record_Type_ID__c;
        RecipeList.add(rec);
        }
        insert RecipeList;
        } 
        }       
}

Trigger 2

trigger CreateRecipeItems on Recipe_Sheet__c (after insert) {

    List<Recipe_Sheet_Item__c> RecipeItemList =new List<Recipe_Sheet_Item__c>();
    List<Recipe_Sheet__c> RecipeList =new List<Recipe_Sheet__c>();
    List<Product_Item__c> ProductItemlist =new List<Product_Item__c>();
    List<Product2> ProductList =new List<Product2>();

    for(Recipe_Sheet__c rec :trigger.new){
        if(rec.Name !=''){       
        ProductList = [select Id,Name,Do_Not_Discount__c,Record_Type_Id__c from Product2 where Id =: rec.Product__c];
        ProductItemList =[select Id,Product__c,Quantity__c,Group__c,Item__c,Length_in_inches__c,External_Wall_Mount_Vaulted_Ceiling__c from Product_Item__c where Product__c =: rec.Product__c];
        Recipelist  =[Select Id,Opportunity__c,Product__c from Recipe_Sheet__c where Id =: rec.id];

        for(Product_Item__c pilist :ProductItemlist ){
        Recipe_Sheet_Item__c ritem = new Recipe_Sheet_Item__c();
        ritem.Recipe_Sheet__c = Recipelist[0].Id;
        ritem.Group__c = pilist.Group__c;
        ritem.Item__c = pilist.Item__c;
        ritem.Quantity__c = pilist.Quantity__c;
        RecipeItemList.add(ritem);
        }
        if (!RecipeItemList.isEmpty()) insert RecipeItemList ;
        } 
        }       
}
