Preheat your oven to 400°F (200°C). Press the tofu between paper towels to remove excess moisture, then cut into 1-inch cubes.
Lightly toss the tofu cubes with olive oil and a pinch of salt and your preferred spices (such as garlic powder and paprika). Spread them out on a baking sheet lined with parchment paper.
Bake the tofu for 20-25 minutes, turning halfway, until the cubes are golden and crispy on the edges.
If not already prepared, cook the quinoa according to package instructions. Allow it to cool slightly.
Rinse the chickpeas and, if using canned, drain well. Measure out the shelled edamame, which can be quickly steamed or microwaved.
In a large bowl, combine the baby spinach, diced red bell pepper, cooked quinoa, edamame, and chickpeas.
Add the baked tofu to the bowl and gently toss everything together. Optionally, season with a squeeze of lemon juice, salt, and pepper to taste.
Serve immediately for a refreshing and protein-packed lunch.
