Add potatoes, 1 tsp salt and enough water to cover (by approx. 1 inch) to a large pot (use same for 4 ppl). Cover and bring to a boil over high heat. Once boiling, reduce heat to medium. Simmer uncovered until potatoes are fork-tender, 10-12 min.

Meanwhile, strip 1 tbsp thyme leaves (dbl for 4 ppl) from stems, then roughly chop.Roughly chop parsley. Slice mushrooms.

Heat a large oven-proof pan over medium heat. When hot, add 1 tbsp butter (dbl for 4 ppl), then swirl the pan until melted, 30 sec. Add mirepoix and peas. Cook, stirring often, until veggies soften slightly, 2-3 min. Add mushrooms, garlic puree and thyme. Cook, stirring often, until mushrooms soften slightly, 3-4 min. Season with salt and pepper.

Add soy sauce, 1 tbsp tomato sauce base (dbl for 4 ppl) and Gravy Spice Blend to the pan with veggies. Cook, stirring often, until veggies are coated, 1-2 min. Add stock powder and 3/4 cup water (dbl for 4 ppl). Bring to a boil. Once boiling, reduce heat to medium-low. Cook, stirring often, until sauce thickens slightly and veggies are tender, 3-4 min.

When potatoes are fork-tender, drain and return them to the same pot, off heat. Mash cream cheese, half the parsley, 1/4 cup milk and 2 tbsp butter (dbl both for 4 ppl) into potatoes until creamy. Season with salt and pepper, to taste. (NOTE: If you don't have an oven-proof pan, transfer filling to a 8x8-inch baking dish for 2 ppl or a 9x13-inch dish for 4 ppl.) Top filling with mashed potatoes, spreading into an even layer.
