Pizza Focaccia - cooking recipe

Ingredients

3 cups gluten-free pizza and pastry flour, plus additional, for dusting
1 pkg (1/4 oz) dried instant yeast
1/4 tsp salt
1 tbsp olive oil
1 lb chicken tenders
1 small onion, finely grated
1/4 cup tomato paste
1 cup grated Cheddar cheese
3 oz sun-dried tomatoes, cut into strips
4 oz baby spinach

Preparation

Sift flour into a bowl. Add yeast and salt. Stir to combine. Make a well in center. Add 1 cup water and oil. Mix to form a soft dough. Turn out onto a lightly floured surface. Knead for 10 mins, or until smooth and elastic. Place in a lightly greased bowl. Cover with plastic wrap. Let stand in a warm place for 45 mins, or until dough has doubled in size.
Meanwhile, heat a large nonstick skillet on medium heat. Spray with no stick cooking spray. Cook chicken for 5-7 mins, turning once, until cooked through. Let stand 5 mins before slicing thinly.
Preheat the oven to 425\u00b0F. Using your fist, punch dough down. Knead on a lightly floured surface until smooth. Roll dough out to fit a 12 x 8-inch baking pan.
Combine onion, tomato paste and 1 tbsp water in a bowl. Spread evenly over dough. Top with grated cheese, chicken, tomatoes and half of spinach. Bake for 30 mins, until golden and crisp. Serve topped with remaining spinach.
