Step 2

2 Mix cream and cream cheese with pesto and lemon juice. Salt and pepper to taste.

Step 3

3 In a large pan over medium-high heat, melt the butter. Add the chicken, season with salt and pepper, and fry until they turn a nice golden brown.

Step 4

4 Place the chicken in a greased 9 x 13" (23 x 33 cm) baking dish, and pour in the cream mixture.

Step 5

5 Top chicken with leek, tomatoes, and cauliflower.

Step 6
