Must have confused myself somewhere along the way, but here is the solution:
<tbody>
<%= for meeting <- @meetings.results do %>
<tbody>
<tr>
<td><%= meeting.date %></td>
<td>
<table>
<tbody>
<%= for speaker <- meeting.speakers do %>
<tr>
<td>
<h4><%= speaker.name %></h4>
</td>
</tr>
<tr>
<td>
<p><%= speaker.title %></p>
</td>
</tr>
<% end %>
</tbody>
</table>
</td>
<td><%= link "Attendees", to: meeting_path(@conn, :show, meeting) %></td>
</tr>
<% end %>
</tbody>
