1 1/2tsp salt
7g easy bake yeast
1tbsp sunflower oil plus extra for greasing

Instructions
Place flour, salt and yeast in large bowl and mix together. Make large well in middle, pour in oil , butter and 300ml warm water, then bring together to make light, soft dough not too sticky. Knead on lightly floured surface for 10mins by hand (5mins by machine), until smooth and elastic. Pop dough into large, lightly oiled bowl, cover with clean tea towel and leave to rise for 45-60mins or until doubled in size.
Divide dough into 2 pieces. Roll out each half on lightly floured surface to square, 1cm thick. Leaving 1cm border around edge, spread each with 1 1/2tbsp mustard, than lay over ham and scatter with grated cheese, tomatoes and thyme. Season and roll up like Swiss roll, sealing seam and sides. With seam on underside, place on lightly oiled baking sheet, cover with tea towel and leave to rise 45-60mins.
Preheat oven to 200C. Remove tea towel and bake for 35-40mins. Cool on wire rack, then wrap tightly in foil for travel.
