No oxo cubes ?? Fry ur onions , make sure ur veg is boiled so it cooks evenly, boil ur rice and when it's done crack a egg and bring together then add to pepper and stick in oven , season after and if u have some cheese top off the pepper at the end :)
Olive oil will work fine. Cook the rice in water and fry it in the olive oil; rub olive oil and some salt and pepper (if you have any) all over the carrots and bake them in the oven till they're soft and delicious.
Omelette and rice , u have all the other ingredient so bang it all together and vallah or u could do stuffed roast pepper with both ingredients or a soup ?? Enjoy
any spices? It can change nothing into something. Maybe an egg hidden in the fridge? If this is truly all you have pop round to mine tomorrow for dinner.
