QuestionExpander Width Problem Pin

I'm trying to create a ListBox, with it's ItemTemplate being an expander, which itself has a list in it.

Here's a pic of what I'm trying to accomplish. Pic
I added colors around each item to highlight what's happening.

Here's the XAML
<ListBox Grid.Row="2"
            Grid.Column="1"
            x:Name="outerList"
            Margin="2,2,2,2"
            Background="Transparent"
            ItemsSource="{Binding RecentItemSections}"
            SelectedItem="{Binding SelectedRecentItemSection}"
            HorizontalAlignment="Stretch"
            BorderBrush="Yellow"
            BorderThickness="2">

    <ListBox.ItemTemplate>

        <DataTemplate>

            <Expander IsExpanded="{Binding IsSectionExpanded}"
                        x:Name="expander"
                        HorizontalAlignment="Stretch"
                        BorderBrush="Red"
                        BorderThickness="2">

                <Expander.Header>
                    <TextBlock Text="{Binding SectionName}"
                                Foreground="White" 
                                Width="{Binding RelativeSource={RelativeSource Mode=FindAncestor,
                                    AncestorType={x:Type ListBoxItem}}, Path=ActualWidth}"/>
                </Expander.Header>

                <ListBox ItemsSource="{Binding RecentItems}"
                            BorderBrush="Green"
                            BorderThickness="5"
                            Margin="2,0,20,0">

                    <ListBox.ItemTemplate>
                        <DataTemplate>

                            <Border BorderBrush="MediumAquamarine"
                                    BorderThickness="2">

                                <StackPanel Orientation="Vertical"
                                        HorizontalAlignment="Stretch">

                                    <TextBlock Text="{Binding ItemName}"
                                            FontSize="12"
                                            Margin="2"/>

                                    <TextBlock Text="{Binding ItemLocation}"
                                            FontSize="10"
                                            Margin="2,0,2,2"/>

                                </StackPanel>

                            </Border>

                        </DataTemplate>
                    </ListBox.ItemTemplate>

                </ListBox>

            </Expander>

        </DataTemplate>

    </ListBox.ItemTemplate>

</ListBox>
As you can see in the pic, the Expander's header is off the right side of the listbox item.

How can I get the expander to fit inside its parent, the ListBox?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
