Since I eat a plant-based diet, tofu and tempeh are on the menu a few times a week. I like to sauté cubed tofu (my favourite is Trader Joe's High-Protein Super Firm Organic Tofu) in a pan on the stove with a little olive oil, garlic powder, and seat salt. Every few minutes, I give the tofu a good stir until it's lightly browned, which takes less than 15 minutes. If I have more time and want a more complex flavour, I'll marinate the tofu or tempeh and then bake it.
Use cooked tofu or tempeh on top of a salad, or pair it with cooked whole grains and vary the flavour my making homemade sauces like this peanut sauce. I also like adding tofu or tempeh to pasta, in a wrap, or taco or as an afternoon snack when I'm craving something salty.
You can food prep other forms of protein like shredded chicken in the Crockpot, ground beef, or Paleo meatballs.
