The all-natural range, called Alexia Select Sides, is for skillet preparation take between 10 and 12 minutes.

Four varieties, Roasted Red Potatoes & Baby Portabella Mushrooms, Roasted Red Potatoes & Italian Inspired Vegetables, Roasted Red Potatoes & Harvest Vegetables and Chipotle Roasted Sweet Potatoes, include three servings as well as oils and spices to complement the dishes.

Michael Smith, brand director at ConAgra Foods, said: "Our consumer research showed that people crave more variety, yet often treat side dishes as an afterthought. With Alexia Select Sides, we're able to deliver premium, all-natural side dishes packed with the flavour of our herb-infused cooking oil and easily prepared in a skillet. Sautéing the vegetable blend creates a tempting aroma and gives the dish more flavour when compared with other frozen vegetables."

The cholesterol and trans-fat free dishes are available for $3.69 in the US.
