you can't go wrong with meat, veggies & some good fats. 20% of 1000 is 200 - so about 50 g of carbs, right? Figure 1 small portion fruit (berries work well) (I'd go for a serving size that gets you maybe 15 g carbs) and fill out the rest of the day with plenty of veggies, without any sugar or flour or potatoes or beans - and you're golden.
Have all the broccoli, asparagus, celery, zucchini, green beans, cucumber, salad greens, salsa, peppers, cauliflower that you want.
Save some room in your calories for some good fats - avocado, butter, real olive oil in your salad dressing, a few nuts and seeds, a few olives, some excellent cheese.
If you're really bored with the eats, reserve some of those carbs for some restrained use of condiments - ketchup, BBQ sauce, teriyaki sauce - if you measure them and plan for it you can still use them and hit your carb goals. Yes - it's mainly sugar and not the best - but if it helps keep you on plan and you still have plenty of veggies in the mix - why not?
