Place the oats, water, and salt in a saucepan. Bring to a boil, reduce heat to low, and simmer until the oats are starting to thicken but aren't yet fully cooked (about 3-5 minutes). Stir in the nutritional yeast, lemon zest and juice, and then add the spinach; cover the oats and allow the spinach to wilt down for about a minute. Then, remove the lid from the oats and stir the spinach in. Continue cooking for another 2-3 minutes, or until the oats are creamy and have reached a desired consistency. If they get overly thick, you can always add a splash of water. Taste and adjust salt and pepper as needed.

While the oats are cooking, you can steam, simmer or microwave the peas till tender; if you prefer, you can also stir them into the oats while they cook (I like to pile mine on top, but it creates another step).

When the oats are ready, top them with the peas, tofu, and hummus. Serve right away.
