How To Display Two Column Grid On Mobile

I am switching from twigmo back to designing a responsive theme for my mobile webstore. With twigmo it was very easy to have a two column grid of products on the homepage of my mobile site.

Now I've been working with the responsive theme I am finding it very difficult to get a similar look. Is there a way to come close to recreating this look?

If I switch to landscape mode in mobile I can see two columns of the grid, but as soon as I switch back to portrait mode it switches back to a single column. I would like it to stay two products in portrait mode.

Thanks for any advice.
