This is what I made last night for dinner, and it was really tasty:
1 long yam, peeled and cut into bite-sized pieces
~1 c frozen peas
2-3 tbsp olive oil
half & half
half an onion, cut in strips
1 tbsp minced garlic
Heat olive oil in large skillet on medium high heat. Add garlic and onions. Once they are sizzling, add yam. While it's cooking, stir frequently and add spices. Cook for about 15 mins or so, and then add peas. Cook until the peas are no longer frozen, and add a generous splash of half and half, and parmesan cheese to taste. Reduce heat to medium low, and cook until the cream thickens.
I served this with a side of spinach and cheese ravioli, but it was great on it's own, and could also go on pasta.
For any vegans out there that find this recipe, it was tasty before the addition of the half & half, so you could serve it like that, or splash in some "motherless milk" and a little nutritional yeast, if you want to have that added creaminess.
