Breakfast: Steel cut oats with berries and walnuts (If you want more sweetness, mash a banana in there too; if you want more creaminess, try adding almond milk!) or overnight oats.
Snack: Any raw fruit or vegetable of your choosing.
Lunch: Big salad with homemade dressing. Pick a base of leafy dark greens (kale, spinach, arugula, etc), add all the raw fruits and veggies you'd like, add a vegetarian protein source (beans, tofu, tempeh, lentils, etc), add a light homemade dressing (vinegar or lemon juice, olive oil, spices, garlic, and/or pepper and whisk). Want an extra crunch? Add seeds and nuts or roasted chickpeas.
Snack: Any raw fruit or vegetable of your choosing and/or chia seed pudding.
Dinner: Salmon and veggies (marinate salmon in garlic, lemon, and olive oil, then bake; veggies can be steamed or roasted with light olive oil) or a big bowl of roasted or steamed veggies with quinoa or farro and plenty of spices.
