You can embed it in the URL of the link, like:
<A HREF="next_page.php?recipe_type=vegetarian&val2=meatismurder">More recipes here</A>
or, you can turn the link into a submit button with some javascript.
<FORM name="myform" action="next_page.php">
<A HREF="" onclick="some_js_stuff();">More recipes here</A>
in the javascript, you need to have:
document.myform.submit() to submit the form.
