Add some products to main menu

[compsoul.dev]

Hello, I just create my own template and I want to add some product to mainmenu.tpl what is the fastest and simplest way to add in the foreach loop two products from current menu category. E.g.

{foreach from=$nodes item=node}
  {import src="product.tpl" category="node.current_id"}
  or
  {getProduct id="node.current_id"}
{/foreach}

  Thank You for help
