Mix the linseed finely. Then mix the linseed, egg, mustard and low-fat quark with a stirring stick and place the mixture on baking paper. Shape a kind of ball with the parchment paper. Put on a second piece of baking paper and roll it out very thinly with the rolling pin. Put the rolled out base with the lower baking paper on a baking sheet and place in the oven for 10 minutes.
For the sauce, chop the tomatoes, sun-dried tomatoes and garlic and mix together with the olive oil, oregano, salt and pepper in a large cup. Put in a hot pan and cook for about 2 minutes, until the garlic aroma is in the nose.
Spread the tomato sauce on the base and top with spinach and broccoli. Then cover with the cheese and bake at 220 ° C for 10 - 15 minutes, depending on how crispy you want.
Get out of the oven and enjoy without a guilty conscience!
