Portobello Burgers and Sweet Potato Fries

Meanwhile, core, seed, and dice 1 tomato. Thinly slice the other tomato. Halve, peel, and thinly slice the onion. Drizzle the portobellos with olive oil, and season on all sides with salt and pepper. Place on another baking sheet with the sweet potatoes and bake 10-12 minutes, until tender.

Meanwhile, heat a drizzle of olive oil in a medium pan over medium heat. Add the onion and diced tomato. Cook, stirring often, until jammy, for 10-15 minutes. Add a splash of water if the jam becomes too thick. Season with salt and pepper.

While the jam cooks, halve, pit, and thinly slice the avocado. Halve the buns, and place in the oven to toast about 5 minutes.
